/**
* @file class_pcb_group.h
* @brief Class to handle a set of BOARD_ITEMs.
* Group parent is always board, not logical parent group.
* Group is transparent container - e.g., its position is derived from the position
* of its members.
* A selection containing a group implicitly contains its members. However other operations
* on sets of items, like committing, updating the view, etc the set is explicit.
