This is a major feature release for a new analysis type labelled 'frame order'. The frame order
theory aims to unify all rotational molecular physics data sources via a single mechanical model.
It is a bridging physics theory for rigid body motions based on the statistical mechanical ordering
of reference frames. Its current implementation is for analysing RDC and PCS data from an internal
alignment to interpret domain or other rigid body motions within a molecule or molecular complex.
