Fix for relax_io.write_spin_data() for when there is no data to write out.

This function will now do nothing. The problem was introduced in the last commit.

Improved the whitespace formatting of the spin data write out of relax_io.write_spin_data().

Now the column sizes are dynamically changed to match the data being written out. This is to fix
the ugly write outs for when the name of the molecule is very long.

Replaced all mention of 'arguments' from the user function docstrings with human readable text.

The state.load user function will now recreate the GUI tabs.

For this, the new state_load observer object has been created. The GUI analysis load_from_store()
is registered with this object. And to prevent fatal racing in the GUI, the state.load user
function operation is now synchronous. The state.load and state.save file arg defaults are now also
set to 'state.bz2'.

Fix for the GUI tests - the ds.tmpfile string is now being created by the base setUp() method.

This is needed to stop files from being created within the relax directory tree.

Removed a printout in the API documentation compilation.

Epydoc docstring fixes.

Import fix.

All of the user_function.object.Table instances in the specific code descriptions are now private.

This hides them from the specific API, and allows the unit tests to pass.

Fix for the prompt UI tables in the help strings for when there is no spacing between rows.

The indexing has changed due to the structure of the user_functions.objects.Table class.
