Detailed Description

Provides alignment subsystem functions to INDI alignment math plugins.

Note

This class is intended to be implemented within a dynamic shared object. If the implementation of this class uses a standard 3 by 3 transformation matrix to convert between coordinate systems then it will not normally need to know the handedness of either the celestial or telescope coordinate systems, as the necessary rotations and scaling will be handled in the derivation of the matrix coefficients. This will normally be done using the three reference (sync) points method. Knowledge of the handedness of the coordinate systems is needed when only two reference points are available and a third reference point has to artificially generated in order to derive the matrix coefficients.
