+Determining Rotors From Frame Pairs or Orthogonal Matrices
+==========================================================
 
 Given two frames that are related by a orthogonal transform, we seek a rotor which enacts the transform. Detail of the mathematics and psuedo code used the create the algorithms below can be found at Allan Cortzen's website.

-There are also some helper functions which can be used to translate matrices into GA frames, so an orthogonal matrix can be directly translated into a Verser.
