Separate MicroAOD test and tag test

Addresses #114 ... separates MicroAODProducers/test/simple_Producer_test.py and TagProducers/test/simple_Tag_test.py, with the latter using the former's output.  The text output and debugging features for tags from the globelikeTreeMakerWithTagSorter.cc are now moved into a new analyzer, which is concluded (after the tag sorter) in simple_Tag_test.py.  Instructions will be updated.
