CROSSPRODUCT3D Vector cross product faster than inbuilt MATLAB cross.

   C = crossProduct3d(A, B) 
   returns the cross product of the two 3D vectors A and B, that is: 
       C = A x B
   A and B must be N-by-3 element vectors. If either A or B is a 1-by-3
   row vector, the result C will have the size of the other input and will
   be the  concatenation of each row's cross product. 

   Example
     v1 = [2 0 0];
     v2 = [0 3 0];
     crossProduct3d(v1, v2)
     ans =
         0   0   6


   Class support for inputs A,B:
      float: double, single
