Fixes for all of the RDC and PCS flags in the frame order target functions.

Converted the frame order target function code to be more like the N-state model.

This matches a number of changes which occurred in the trunk (via branches). The alignment index
has been changed from 'i' to 'align_index' for clarity. The 'rdc_const' and 'pcs_atoms' keyword
arguments have been renamed to 'dip_const' and 'atomic_pos' respectively to match the N-state model.
And proper support for the interatomic data design for the RDCs has been added.

The frame order system tests are now showing the number of integration points as a debug message.

Fix for the frame order _minimise_setup_rdcs() method for handling multiple unit vectors.

Fix for the Frame order _minimise_setup_pcs() method for how atomic positions are now stored.

This will always be a rank-2 array, even with a single position, and the method now handles this.

Modified the base script for the CaM frame order system tests to not average the atomic positions.

This is needed for the multiple vectors used in the RDC calculation.

Updates to the frame order module for the interatomic data design.

This includes import cleanups.
