Coordinate System Math Comparator tolerances are too tight

Description

The coordinate system MathComparator? is an object used to compare two coordinate system definitions to see if they are mathematically equivalent; i.e. would produce the same numeric results. The tolerances used to compare definition components as applied to CS-MAP definitions are too tight. For example, the tolerance used to compare ellipsoid radii is 1.0E-13. Thus, definitions which are essentially the same, although not precisely identical, will not produce a positive comparison.

Additionally, the MathComparator? will compare items in the definition which would not affect the numeric results produced by an instantiation of the definition, such as the useful range of the coordinate system. These additional comparisions should be removed.
