Eliminated the unused Set_processor_property_command class.

Eliminated the unused Get_name_command class.

Clean up of the Exit_command.

This no longer has an __init__() method, and has proper descriptions via docstrings and comments.

Shifted the Multi_processor.run() method up a level to Processor.run().

This completes one of the TODOs, and will be needed to avoid code duplication for handling the new
data_upload() and data_fetch() API methods. This run() method now works for the uni-processor, as
the Uni_processor.on_master() method which always returns True has been reactived, so the
Uni_processor.run() method has been deleted.

Eliminated the completely unused create_slaves() Processor method.

The processor instances now have a data storage container.

This will be used by the data_upload() and data_fetch() API methods.

Implemented the mpi4py processor fabric data_upload() method.

This currently sends the data out into the ether using an MPI.COMM_WORLD.send() call with the
tag 10 which will be reserved for sending data into the data store. Somehow this needs to be caught
and stored by the slaves.

Updated the second multi-processor test implementation to use the new data_upload() API function.

The multi.data_upload() API fn now forwards the call to the Processor classes.

This still needs an implementation for each processor fabric.

Created the stub functions data_fetch() and data_upload() for the multi-processor API.
