		Test cases for the following not added. They perform operations 
		on underlying LLXformMatrix	and LLVector3 elements which have
		been unit tested separately. 
		Unit Testing these functions will basically require re-implementing
		logic of these function in the test case itself

		1) void WorldMatrixChildren();
        2) void updateWorldMatrixParent();
        3) void updateWorldPRSParent();
        4) void updateWorldMatrix();
        5) LLXformMatrix *getXform() { return &mXform; }
        6) void setConstraintSilhouette(LLDynamicArray<LLVector3>& silhouette);
        7) void clampRotation(LLQuaternion old_rot, LLQuaternion new_rot);
