"""Euler-angle to matrix and matrix to Euler-angle utility routines

This module provides utility routines to convert between 4x4 homogeneous
transformation matrices and Euler angles (and vice versa). It supports 
all six rotation orders ('xyz','xzy','yxz','yzx','zxy','zyx') for rotations
around body axes.

Two primary functions are provided:

- rotation( theta, order='xyz' ): given input rotation angles in radians
