Fixes for the relaxation curve-fitting specific return_data() method.

Strangely, it appears as if this method is never used.

Added some consistency to the specific analysis API base class.

The return_data() method argument has been changed from 'spin' to 'data_id', as the data from the
base_data_loop() methods are often not spin containers.

Small docstring fix.

The N-state model _check_rdcs() method now skips deselected interatomic data containers.

A FIXME comment has also been added to highlight a possible future problem.

Added new checks in the N_state_model.test_metal_pos_opt system test.

These are for structures which should not be in the deselected spins and interatomic containers

Big data store clean up fix for the N-state model.

The N-state model specific base_data_loop() method now skips deselected interatomic data containers
and spins. This prevents a lot of junk data being created in the data pipe, for example back
calculated and Monte Carlo simulation RDC and PCS data.
