[Halld-offline] BCAL library

[Paul Mattione]

High level: Get the DBCALShower objects from JANA (no tag).  
 
I highly recommend using the janadot plugin.  I think you can use it along with the factory autoactivate option … but I can’t remember how that works.  What I usually do is just run it alongside another plugin that is (in this case) using DBCALShower objects.  It then prints instructions to screen on how to convert the dot file to pdf.

I suppose I could go through the code, but I thought I would ask the group for guidance first.
