Detailed Description

Representation of a geometric point in a 3-D cartesian space.

This class may become a template class in the future, but right now I just need to get something working with pure doubles. A geometric point is distinguished from, but related to, the a geometric vector. A geometric point's coordinates transform differently from those of a geometric vector when a change of coordinate system occurs.
