The controller window does not lock the GUI after clicking 'View -> Controller'.

Show() is used instead of ShowModal().

Created a basic, though not yet functional, assemble_data() method.

This will now pack the all the model-free data into a container and return that instead.

Added a module for the GUI base classes.

This currently contains only a single empty class to be used as a container.

The relax controller window is shown straight after the global model choice dialog.

Import spelling mistake fix.

Big changes in how the automatic model-free protocol is executed.

The call to gui_bieri.execution.calc_modelfree.start_modelfree() has been eliminated. This has been
replaced by a call to self.execute(). This new method assembles the data required for the protocol
from the relax data store (by calling self.assemble_data() which doesn't exist yet), and then starts
and stores the thread which is executing dAuvergne_protocol.

Removed all the model-free code from the controller module.

Added the empty class Thread_container to be used to store the calculation thread info.

Added a list (self.calc_threads) for holding the calculation thread IDs.

This can be used for controlling the threads by the controller window.

Simplified the local variable names in add_execute_relax().

The following have been renamed and shifted into the local namespace:
self.label_5_copy_1_copy_3 -> label
self.relax_start_modelfree -> button
exec_relax_copy_1_copy_3 -> sizer
