Subject: add a GPU class to handle both the gpu context and module; since the
 geometry requires global device pointers, there should be a one to one
 correspondence between modules and contexts. the current plan is to perform
 all gpu operations within this class. also add a simple color map to display
 hit pmt charge and timing information.
