Vcross()
vcross(<vector>,<vector>[,<delim>][, <output delim> ])
Returns the cross product of two vectors. The cross product of two vectors is a vector.
| a b c |
(a,b,c) X (d,e,f) = det | d e f | = i(bf-ce) + j(cd-af) + k(ae-bd)
| i j k |
where i, j, and k are taken as unit vectors in Cartesian space.
