Shifted the mpi4py processor module functions broadcast_command() and ditch_all_results() into the class.

These have been turned into private methods.

Redesigned how the multi-processor package terminates program execution.

The Processor.exit() method has been introduced to perform this action. By default (used by the
uni-processor fabric), the method does nothing. The mpi4py_processor.py module functions exit() and
exit_mpi() have been merged into the Mpi4py_processor.exit() method.

Spelling fix for a number of the processor method names.

Fully documented the Processor.run() method via comments.

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.
