Removed the functions not used by relax from the 'generic_fns.pipes' module.

The functions 'eliminate_unused_pipes()' and 'list_of_pipes()' have been deleted as they are not
used anywhere within relax. The unit test for the 'eliminate_unused_pipes()' has also been deleted.

Fixed the setting of the current data pipe so that the 'test_deletion()' unit test passes.

The current data pipe was not being set to None by the 'generic_fns.pipes.delete()' if the deleted
pipe is the current pipe.

Fixed the setting of the current data pipe so that the 'test_creation()' unit test passes.

The current data pipe was not being set to the new data pipe created by the function
'generic_fns.pipes.create()'.

Fixed the 'test_deletion_fail()' unit test.

The error throw was RelaxNoRunError and not RelaxError.

Rewrote the 'generic_fns.pipes.delete()' function.

Added a tearDown() method to the 'test_suite/unit_tests/generic_fns/test_pipes.py' file.

The relax data storage object is reset as the data added to it from different tests was clashing.
The method allows the 'test_creation_fail' unit test to pass.

Fixed the function generic_fns.pipes.create().

The relax data store singleton method 'add()' has been deleted as the method required the first
argument to be the singleton instance. Instead the functionality has been shifted into the
generic_fns.pipes.create() function. The unit tests have been modified for the new setup.

All references to 'run' in the file 'test_suite/unit_tests/generic_fns/test_pipes.py' have been
replaced with 'pipe'.

Added unit tests for the relax data storage singleton class Data from the 'data' module.

Fixed the problems with the classes of the 'data.mol_res_spin' module.

The add_item() methods of the list type classes have been modified. For the MoleculeList class the
'mol_name' argument has been added and the MoleculeContainer.__init__() method accepts this argument
as well. The 'res_name', 'res_num', 'spin_name', 'spin_num', and 'select' have similarily been
added.

Bug fix.

The import statement for the pipes module has been removed from 'generic_fns.main'.
