simplified configuration schema
more stuff in PHP variables
Building lib area for classes
Added lib file and test to set up php classes

Classes are for systems and datasources so we can have instances of
datasources on a report and re-use the display logic.
move test-lib to tests folder
adjust settings now that test is in tests
Set up a second test instance of a datasource
Got first returned item from Sheetrock as itemKey
just need schema array working now
