 * @description
 * SubHeader module
 *
 *  Subheaders are special list tiles that delineate distinct sections of a
 *  list or grid list and are typically related to the current filtering or
 *  sorting criteria. Subheader tiles are either displayed inline with tiles or
 *  can be associated with content, for example, in an adjacent column.
 *
 *  Upon scrolling, subheaders remain pinned to the top of the screen and remain
 *  pinned until pushed on or off screen by the next subheader. @see [Material
 *  Design Specifications](https://www.google.com/design/spec/components/subheaders.html)
 *
 *  > To improve the visual grouping of content, use the system color for your subheaders.
