Subject: Major steps towards implementing the policy component. Identified and
 reacted to the priority inversion problem we have in texturefetch.  Includes
 the introduction of a priority_queue for the requests that are ready.  Start
 some parameterization in anticipation of having policy_class everywhere. 
 Removed _assert.h which isn't really needed in indra codebase.  Implemented
 async setPriority request (which I hope I can get rid of eventually along
 with all priorities in this library).  Converted to using unsigned int for
 priority rather than float.  Implemented POST and did groundwork for PUT.
