/********************************************************************
*
*       File:           gfCParkSlotStaffComponent.h
*
*       Purpose:        Attached to a placed building; a tap deploys/recalls
*                               staff to its slot (or dispatches a repairer - see
*                               toggleStaffing). Also tints the building by state.
*                               A small message listener rather than a HOG collectable
*                               subclass, whose machinery doesn't apply here.
