            /*
             * Our basic approach here for event handlers is that we listen for a down event (mousedown or touchstart).
             * Once we have a down event, we need to work out whether we have a click, a drag, or a
             * hold.  A click would sort the grid (if sortable).  A drag would be used by moveable, so
             * we ignore it.  A hold would open the menu.
             *
             * So, on down event, we put in place handlers for move and up events, and a timer.  If the
             * timer expires before we see a move or up, then we have a long press and hence a column menu open.
             * If the up happens before the timer, then we have a click, and we sort if the column is sortable.
             * If a move happens before the timer, then we are doing column move, so we do nothing, the moveable feature
             * will handle it.
             *
             * To deal with touch enabled devices that also have mice, we only create our handlers when
             * we get the down event, and we create the corresponding handlers - if we're touchstart then
             * we get touchmove and touchend, if we're mousedown then we get mousemove and mouseup.
             *
             * We also suppress the click action whilst this is happening - otherwise after the mouseup there
             * will be a click event and that can cause the column menu to close
             *

       * Each attribute automatically becomes a column in your grid.  This array could, for example, be sourced from

       * This is the most flexible approach as it allows you to replace $scope.data whenever you feel like it without

       *
       * Alternatively you can directly set the data array:

     *  @name updateColumnWidths
     *  @propertyOf  ui.grid.class:GridRenderContainer
     *  @description Determine the appropriate column width of each column across all render containers.
     *
     *  Column width is easy when each column has a specified width.  When columns are variable width (i.e.
     *  have an * or % of the viewport) then we try to calculate so that things fit in.  The problem is that
     *  we have multiple render containers, and we don't want one render container to just take the whole viewport
     *  when it doesn't need to - we want things to balance out across the render containers.
     *
     *  To do this, we use this method to calculate all the renderContainers, recognising that in a given render
     *  cycle it'll get called once per render container, so it needs to return the same values each time.
     *
     *  The constraints on this method are therefore:
     *  - must return the same value when called multiple times, to do this it needs to rely on properties of the
     *    columns, but not properties that change when this is called (so it shouldn't rely on drawnWidth)
     *
     *  The general logic of this method is:
     *  - calculate our total available width
     *  - look at all the columns across all render containers, and work out which have widths and which have
     *    constraints such as % or * or something else
     *  - for those with *, count the total number of * we see and add it onto a running total, add this column to an * array
     *  - for those with a %, allocate the % as a percentage of the viewport, having consideration of min and max
     *  - for those with manual width (in pixels) we set the drawnWidth to the specified width
     *  - we end up with an asterisks array still to process
     *  - we look at our remaining width.  If it's greater than zero, we divide it up among the asterisk columns, then process
     *    them for min and max width constraints
     *  - if it's zero or less, we set the asterisk columns to their minimum widths
     *  - we use parseInt quite a bit, as we try to make all our column widths integers

   *  @element div
   *  @restrict A
   *
   *  @description Stacks on top of ui.grid.uiGridCell to provide in-line editing capabilities to the cell
   *  Editing Actions.
   *
   *  Binds edit start events to the uiGridCell element.  When the events fire, the gridCell element is appended
   *  with the columnDef.editableCellTemplate element ('cellEditor.html' by default).
   *
   *  The editableCellTemplate should respond to uiGridEditConstants.events.BEGIN\_CELL\_EDIT angular event
   *  and do the initial steps needed to edit the cell (setfocus on input element, etc).
   *
   *  When the editableCellTemplate recognizes that the editing is ended (blur event, Enter key, etc.)
   *  it should emit the uiGridEditConstants.events.END\_CELL\_EDIT event.
   *
   *  If editableCellTemplate recognizes that the editing has been cancelled (esc key)
   *  it should emit the uiGridEditConstants.events.CANCEL\_CELL\_EDIT event.  The original value
   *  will be set back on the model by the uiGridCell directive.
   *
   *  Events that invoke editing:
   *    - dblclick
   *    - F2 keydown (when using cell selection)
   *
   *  Events that end editing:
   *    - Dependent on the specific editableCellTemplate
   *    - Standards should be blur and enter keydown
   *
   *  Events that cancel editing:
   *    - Dependent on the specific editableCellTemplate
   *    - Standards should be Esc keydown
   *
   *  Grid Events that end editing:
   *    - uiGridConstants.events.GRID_SCROLL

   * <div class="alert alert-warning" role="alert"><strong>Beta</strong> This feature is ready for testing, but it either hasn't seen a lot of use or has some known bugs.</div>
   *
   * This module provides grouping of rows based on the data in them, similar
   * in concept to excel grouping.  You can group multiple columns, resulting in
   * nested grouping.
   *
   * In concept this feature is similar to sorting + grid footer/aggregation, it
   * sorts the data based on the grouped columns, then creates group rows that
   * reflect a break in the data.  Each of those group rows can have aggregations for
   * the data within that group.
   *
   * This feature leverages treeBase to provide the tree functionality itself,
   * the key thing this feature does therefore is to set treeLevels on the rows
   * and insert the group headers.
   *
   * Design information:
   * -------------------
   *
   * Each column will get new menu items - group by, and aggregate by.  Group by
   * will cause this column to be sorted (if not already), and will move this column
   * to the front of the sorted columns (i.e. grouped columns take precedence over
   * sorted columns).  It will respect the sort order already set if there is one,
   * and it will allow the sorting logic to change that sort order, it just forces
   * the column to the front of the sorting.  You can group by multiple columns, the
   * logic will add this column to the sorting after any already grouped columns.
   *
   * Once a grouping is defined, grouping logic is added to the rowsProcessors.  This
   * will process the rows, identifying a break in the data value, and inserting a grouping row.
   * Grouping rows have specific attributes on them:
   *
   *  - internalRow = true: tells us that this isn't a real row, so we can ignore it
   *    from any processing that it looking at core data rows.  This is used by the core
   *    logic (or will be one day), as it's not grouping specific
   *  - groupHeader = true: tells us this is a groupHeader.  This is used by the grouping logic
   *    to know if this is a groupHeader row or not
   *
   * Since the logic is baked into the rowsProcessors, it should get triggered whenever
   * row order or filtering or anything like that is changed.  In order to avoid the row instantiation
   * time, and to preserve state across invocations, we hold a cache of the rows that we created
   * last time, and we use them again this time if we can.
   *
   * By default rows are collapsed, which means all data rows have their visible property
   * set to false, and only level 0 group rows are set to visible.

   *
   * This module provides the ability to import data into the grid. It
   * uses the column defs to work out which data belongs in which column,
   * and creates entities from a configured class (typically a $resource).
   *
   * If the rowEdit feature is enabled, it also calls save on those newly
   * created objects, and then displays any errors in the imported data.
   *
   * Currently the importer imports only CSV and json files, although provision has been
   * made to process other file formats, and these can be added over time.
   *
   * For json files, the properties within each object in the json must match the column names
   * (to put it another way, the importer doesn't process the json, it just copies the objects
   * within the json into a new instance of the specified object type)
   *
   * For CSV import, the default column identification relies on each column in the
   * header row matching a column.name or column.displayName. Optionally, a column identification
   * callback can be used.  This allows matching using other attributes, which is particularly
   * useful if your application has internationalised column headings (i.e. the headings that
   * the user sees don't match the column names).
   *
   * The importer makes use of the grid menu as the UI for requesting an
   * import.

       * If we're scrolling up we scroll to the first row of the old data set -
       * so we're assuming that you would have gotten to the top of the grid (from the 20% need more data trigger) by

       * assuming that you would have gotten to the bottom of the grid (from the 80% need more data trigger) by the time
       * the data comes back.
       *
       * Neither of these are good assumptions, but making this a smoother experience really requires
       * that trigger to not be a percentage, and to be much closer to the end of the data (say, 5 rows off the end).  Even then

  /**
   * @ngdoc overview
   * @name ui.grid.treeBase
   * @description
   *
   * # ui.grid.treeBase
   *
   * <div class="alert alert-warning" role="alert"><strong>Beta</strong> This feature is ready for testing, but it either hasn't seen a lot of use or has some known bugs.</div>
   *
   * This module provides base tree handling functions that are shared by other features, notably grouping
   * and treeView.  It provides a tree view of the data, with nodes in that
   * tree and leaves.
   *
   * Design information:
   * -------------------
   *
   * The raw data that is provided must come with a $$treeLevel on any non-leaf node.  Grouping will create
   * these on all the group header rows, treeView will expect these to be set in the raw data by the user.
   * TreeBase will run a rowsProcessor that:
   *  - builds `treeBase.tree` out of the provided rows
   *  - permits a recursive sort of the tree
   *  - maintains the expand/collapse state of each node
   *  - provides the expand/collapse all button and the expand/collapse buttons
   *  - maintains the count of children for each node
   *
   * Each row is updated with a link to the tree node that represents it.  Refer {@link ui.grid.treeBase.grid:treeBase.tree tree documentation}
   * for information.
   *
   *  TreeBase adds information to the rows
   *  - treeLevel: if present and > -1 tells us the level (level 0 is the top level)
   *  - treeNode: pointer to the node in the grid.treeBase.tree that refers
   *    to this row, allowing us to manipulate the state
   *
   * Since the logic is baked into the rowsProcessors, it should get triggered whenever
   * row order or filtering or anything like that is changed.  We recall the expanded state
   * across invocations of the rowsProcessors by the reference to the treeNode on the individual
   * rows.  We rebuild the tree itself quite frequently, when we do this we use the saved treeNodes to
   * get the state, but we overwrite the other data in that treeNode.
   *
   * By default rows are collapsed, which means all data rows have their visible property
   * set to false, and only level 0 group rows are set to visible.
   *
   * We rely on the rowsProcessors to do the actual expanding and collapsing, so we set the flags we want into
   * grid.treeBase.tree, then call refresh.  This is because we can't easily change the visible
   * row cache without calling the processors, and once we've built the logic into the rowProcessors we may as
   * well use it all the time.
   *
   * Tree base provides sorting (on non-grouped columns).
   *
   * Sorting works in two passes.  The standard sorting is performed for any columns that are important to building
   * the tree (for example, any grouped columns).  Then after the tree is built, a recursive tree sort is performed
   * for the remaining sort columns (including the original sort) - these columns are sorted within each tree level
   * (so all the level 1 nodes are sorted, then all the level 2 nodes within each level 1 node etc).
   *
   * To achieve this we make use of the `ignoreSort` property on the sort configuration.  The parent feature (treeView or grouping)
   * must provide a rowsProcessor that runs with very low priority (typically in the 60-65 range), and that sets
   * the `ignoreSort`on any sort that it wants to run on the tree.  TreeBase will clear the ignoreSort on all sorts - so it
   * will turn on any sorts that haven't run.  It will then call a recursive sort on the tree.
   *
   * Tree base provides treeAggregation.  It checks the treeAggregation configuration on each column, and aggregates based on
   * the logic provided as it builds the tree. Footer aggregation from the uiGrid core should not be used with treeBase aggregation,
   * since it operates on all visible rows, as opposed to to leaf nodes only. Setting `showColumnFooter: true` will show the
   * treeAggregations in the column footer.  Aggregation information will be collected in the format:
   *
   * ```
   *   {
   *     type: 'count',
   *     value: 4,
   *     label: 'count: ',
   *     rendered: 'count: 4'
   *   }
   * ```
   *
   * A callback is provided to format the value once it is finalised (aka a valueFilter).
