vector class

Vector Class
created by: Jared Hopf 2003

Description:
The purpose of this assignment is to design a class for a three dimensional vector. Vectors are very useful in a variety of areas of computer science, like Graphics, Simulations, and Numerical methods, As well, vectors are useful for physics problems, math/calculus problems and other areas.
The vector class should have the following operations:

	setting the vectors values.
	Adding one vector to another.
	Subtracting one vector from another.
	Scaling the vector by a scalar.
	Normalizing the vector.
	Length of a vector.
	Dot Product of two vectors.
	Cross product of two vectors. ( 3D vector only )
	Distance between two vectors.
