angle
	Operation: Returns the radian angle between two vectors 
	Supported Data types: vector.  Returns float
		float angle( vector vector1, vector vector2)
	Example: angle(<<2,-1,1>>,<<1,1,2>>) Returns 1.0472 radians, which equals 60 degrees.
cross
	Operation: Returns the cross product of two vectors 
	Supported Data types: vector
		vector cross(vector vector1, vector vector2)
	Example: cross(<<1,2,-2>>,<<3,0,1>>) Returns <<2, -7, -6>>
dot
	Operation: Returns the floating point dot product of two vectors. The dot product takes two vectors as arguments and returns a scalar value 
	Supported Data types: vector.  Returns float
		float dot(vector vector1, vector vector2)
	Example: dot(<<1,2,-2>>,<<3,0,1>>) Returns 1. 
	               The dot product of this example is (1 * 3) + (2*0) + (-2*1), which equals 1
mag
	Operation: Returns the magnitude of a vector. This is the length of the vector. 
	Supported Data types: Vector.  Returns float
		float mag(vector vector)
	Example: mag(<<7,8,9>>) Returns 13.928
	               This is the same as Sqrt( 72 + 62 +  92); Returns 13.928
rot
	Operation: Returns a vector that represents the position of a point after it's rotated a specified number of radians about a specified axis. 
	                   Rotation is counter-clockwise as viewed downward from the axis end position. 
	Supported Data types: vector, float
		vector rot(vector point, vector axis, float angle )
		point is the position of a point in the world coordinate system. 
		axis is the axis around which the point rotates. The axis is a line that passes through the origin and the specified axis position. 
		angle is the number of radians the point rotates. 

	Example: rot(<<3,3,0>>,<<1,0,0>>,0.5) Returns <<3, 2.633, 1.438>>
	               This is a vector representing the position of point <<3,3,0>> after rotating it 0.5 radians around the axis represented by <<1,0,0>>
unit
	Operation: Returns the unit vector corresponding to a vector. 
	                   The unit vector has the same direction as the specified vector, but with a magnitude of 1
 
	Supported Data types: vector
		vector unit( vector vector)
	Example: unit(<<1,1,1>>) Returns <<0.577, 0.577, 0.577>>
