quat:

---------------------------------------------------------------------------
   Create an object of class quat. You can input:
   4-by-1 matrix - assumed to be a quaternion
   3-by-1 matrix - assumed to be an array of angles
   3-by-3 matrix - assumed to be a transformation matrix
---------------------------------------------------------------------------
   Form:
   q = quat( x )
---------------------------------------------------------------------------

   ------
   Inputs
   ------
   x       (3,1) Quaternion
           (3,3) Matrix
           (3,1) Array of angles

   -------
   Outputs 
   -------
   q      (1,1) Object of class  quaternion.
