Details:

I put them all in two patches - hope this is ok. The first patch has modified
files, the second new files. These functions were developed to support a
transform class (e.g. robotics) which I hope to submit as a separate package
sometime later. 

The changes:

  q2rot.m
Function now accepts multiple quaternions as input. Minor adjustments. 

  rot2q.m
Angle argument may be a vector or matrix, resulting in quaternions of the same
size representing rotations around single axis argument. The axis now has to
be a column vector. Added basic test for consistency against q2rot.

  rotm2q.m
Convert a 3x3 rotation matrix to a unit quaternion.

  @quaternion/mean.m
Take the mean of a quaternion object - functions like normal mean but on each
component.

  @quaternion/numel.m
Number of quaternions in an object.
  
  test_quaternion.m
Updated with new tests.
