A project for Calc 3 related classes.
The Vectors package contains several immutable classes related to the basic storage of objects in 3D space,
including Line, Plane, Point, and Vector. These classes store these concepts in an easy to use way.
All of these use Number to store their values, rather than double or other floating point values.
The Number class is a wrapper class for BigDecimal that provides an exact way to store values,
without some of the disadvantages of BigDecimal.
It is used throughout the program to store values.
The Functions package provides a bunch of classes related to storing and parsing functions.
These functions represent what would normally be called a function in mathematics.
