This module contains functions related to rotations of coordinate frames.
Only the following functions are implemented currently:
- angle2dcm: Convert Euler Angles to Direct Cosine Matrix.
- dcm2angle: Convert a Direct Cosine Matrix to Euler Angles.
A roadmap is not defined yet, but I expect to add many functions related to 3D rotations using Quaternions, Euler axes, Rodrigues parameters, etc.
