bool	IsEqual (GVec theOther, double theLinearTolerance, double theAngularTolerance)
	Returns True if the two vectors have the same magnitude value and the same direction. The precision values are theLinearTolerance for the magnitude and theAngularTolerance for the direction.

bool	IsNormal (GVec theOther, double theAngularTolerance)

	Computes the angular value between <me> and <theOther> Returns the angle value between 0 and PI in radian.
