Associations are partially working

There are new unit tests for associations that leverage the sblim client library. Found that much of the functionality was there but I still have a few things to work out. I really like the new testing framework and how it leverages a 3rd party client library. I'm also breaking the tests down into the various functional CIMOM units defined by DMTF. Looking at the specs I might be able to implement pulled enumerations without much trouble.
