Working calling from CLI for Fidelity. Still need to clean up the unit test.

Major refactoring. Finalized CLI interface to be one arg of a quoted pipe expression. Enhanced tests to cover new CLI interface with one call and chained call. Added individual unit tests for each data source calling from py. Added runner to run batch calls (like piped) from Py -- not tested yet.
