1) Created a DummDataPlugin in SamplePlugin module.

1) Created a DummDataPlugin in SamplePlugin module.

		- DummyDataPlugin is a sligh improvment over QuantumEchoPlugin in that
           the plugin returns hard-coded data structures.

2) Created a CLI that enabled quantum plugin writers to test their plug-in implementation.

		- Currently I am using DummyDataPlugin to test and run the CLI
           but if anybody has another better Quantum plug-in, please modify
           manager.py to use your plug-in and drive the plug-in using the CLI.
        - Running the CLI against wider variety of plug-ins will help the CLI
           evolve and improve. Please free to send patches.

3) TODO: list

	- Finalize the plug-in data model
    - Finalize the exception and make the plug-in throw exceptions
	- Write unit tests for plug-in qualification and CLI testing.
