Detailed Description

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

This class may become a template class in the future, but right now it is based on pure doubles so that I can get something running quickly. A geometric vector is distinguished from, but related to, the a geometric point. A geometric point's coordinates transform differently from those of a geometric vector when a change of coordinate system occurs.
