Feature/brian prototype readsets

Oh boy!  This was done about 30 days ago.  What I was trying to do was add the concept of a "ReadSet" and "Reads" to our system.  I didn't actually store the reads from BAM files in our DB.  Instead it stores a pointer to the filesystem BAM file.  This is not ideal but is a bridge that lets us explore storing BAM data without having to do a full implementation.

There's still work to be done here but I think it's working enough to merge into develop.  Be careful if it really does cause problems, I don't want to destabilize develop since Brian and Jonathon need a place to code.
