Views Bulk Operations Group Select

Provides a new Views style format "VBO Group Select" that allows for the selection of all lower-level grouped results via a click of a single button; this is useful for when you want users to be able to easily select groups of results, and provides a middle-ground between selecting results one by one and using 'Select All' to select every result in every group.

Note that this plugin works on the display-layer only, meaning that it will only capture results that are actually displayed on the page being viewed.
