##  This function returns the same toric code as in J. P. Hansen, "Toric
##  surfaces and error-correcting codes", except that the polytope can be
##  more general This is a truncated RS code. <L> is a list of integral
##  vectors (in Hansen's case, <L> is the list of integral vectors in a
##  polytope) and <F> is the finite field. The characteristic of <F> must
##  be different from 2.
