Merge pull request #2 from jputney/master

add a little testing and logging examples
refactored method names.  Added code to verify auditConfig table exists.  Added some tests.  Started changing over to slf4j loggers.
added liquibase for unit testing.  Starting to address loading/reading configuration tables.
added classes to hold the configuration data from the config tables and the meta data for the database tables.  Now have code to load meta data for each table and column.  Next step is to actually bump the meta data up against the config and generate some SQL to make audit tables.
modified some logging/error handline
