* @ngdoc directive
* @name shape
* @requires Attr2Options
* @description
* Initialize a Google map shape in map with given options and register events
* The shapes are:
* . circle
* . polygon
* . polyline
* . rectangle
* . groundOverlay(or image)
*
* Requires: map directive
*
* Restrict To: Element
*
* @param {Boolean} centered if set, map will be centered with this marker
* @param {String} <OPTIONS>
* For circle, [any circle options](https://developers.google.com/maps/documentation/javascript/reference#CircleOptions)
* For polygon, [any polygon options](https://developers.google.com/maps/documentation/javascript/reference#PolygonOptions)
* For polyline, [any polyline options](https://developers.google.com/maps/documentation/javascript/reference#PolylineOptions)
* For rectangle, [any rectangle options](https://developers.google.com/maps/documentation/javascript/reference#RectangleOptions)
* For image, [any groundOverlay options](https://developers.google.com/maps/documentation/javascript/reference#GroundOverlayOptions)
* @param {String} <MapEvent> Any Shape events, https://developers.google.com/maps/documentation/javascript/reference
* @example
* Usage:
* <map MAP_ATTRIBUTES>
* <shape name=SHAPE_NAME ANY_SHAPE_OPTIONS ANY_SHAPE_EVENTS"></MARKER>
* </map>
