Added some comments for the import statements.

The open_read_file function is now imported as well.

Modified the unit tests for generic_fns.state to import from relax_io.

The function open_write_file is now imported (although it doesn't currently exist).

Renamed the relax io module to relax_io as it clashes with the Python io module.

Removed the old State class from the namespace of 'self.relax.generic'.

Change of the internal structure of the generic_fns.state module.

The State class has been eliminated and its methods load() and save() have been converted to module
functions.

Added a unit test for the generic_fns.state.save() function.

Added the framework for implementing unit tests for the generic_fns.state module.

Bug fix to make the test suite work again.
