Quaternions
===========
Note that all these functions work with single quaternions and quaternion vectors,
as well as with arrays containing these.
Quaternion class
----------------
- quat.Quaternion ... class, including overloading for multiplication and
division (e.g. "quatCombined = quat1 * quat2"), import and export
Functions for working with quaternions
--------------------------------------

- quat.quatinv ... Quaternion inversion
- quat.quatmult ... Quaternion multiplication
Conversion routines - quaternions
---------------------------------
- quat.deg2quat ... Convert number or axis angles to quaternion vectors

- quat.quat2vect ... Extract the vector part from a quaternion
- quat.rotmat2quat ... Convert a rotation matrix to the corresponding quaternion
- quat.vect2quat ... Externd a quaternion vector to a unit quaternion.
- quat.vel2quat ... Calculate orientation from a starting orientation and angular velocity.
Rotation Matrices
=================
Definition of rotation matrices
-------------------------------
- rotmat.R1 ... 3D rotation matrix for rotation about the 1-axis
- rotmat.R2 ... 3D rotation matrix for rotation about the 2-axis
