Add some tests for R&D
Change from JCR based API's for "property" retrieval, to Resource/ValueMap based handling.

Performance for the tests, wigth Logging enabled went from about 30s to 50-55 seconds.  10 seconds of that is a "wait" to give me time to attach a profiler.  So we went from ~20s to 40-45s.  But it works.  We can address performance later.
