Added some epydoc @attention fields to the multi-processor API.

Created the fetch_data_store() multi-processor API function.

This simply returns the data store of the same processor as the calling code. The 2nd test
implementation now uses this code path.

Alphabetical ordering of methods.

The 2nd test implementation's slave command now uses the fetch_data() API function.

This is to obtain the invariant data pre-sent by the master to the slaves.

Renamed the multi-processor API data_fetch() function to fetch_data(), and implemented it.

Renamed data_upload() to send_data_to_slaves() and made it more specific.

The rank argument has been dropped, and now the API function and Processor methods are used solely
for transferring data from the master to all slave processors.

The multi-processor data_fetch() API function is now used to obtain the total_length variable.

Fix for the Processor.data_upload() method.

The self.run_command_queue() method is no longer being used. Instead the add_to_queue() method is
being used to queue up the slave commands, and the run_queue() method is being called at the end to
flush the queue.

Fixes and clean up of the slave to master transfer mechanism for result commands.

The master_queue_command() and master_receive_result() methods are now defined at the Processor
level (but call raise_unimplemented()). Full epydoc docstrings and comments have been added
everywhere. The 2 methods have now been defined for uni-processor fabric, and simply hold the
command in a temporary variable.

Shifted the self.threaded_result_processing flag into the base Processor class where it belongs.
