VECNORMALIZE: Normalize the vectors.
 
 Calling Sequence:
 
   nvec = vecnormalize(vec);
 
 INPUT:
 
   vec		: An array of column vectors represented by a matrix of
 		size (dim,nv), where is the dimension of the vector and
 		nv the number of vectors.

 OUTPUT:
 
   nvec		: Normalized vectors, matrix the same size as vec.
 
 Description:
 
   Normalizes the array of vectors, returning the unit vectors.
 
 Examples:
 
   Normalize the two vectors (0.0,2.0,1.3) and (1.5,3.4,2.3)

   nvec = vecnormalize([0.0 1.5; 2.0 3.4; 1.3 2.3]);
