This function finds G1 discontinuities on a B-surface.


This function will return the discontinuities of a B-surface.

The parameters will be returned in increasing parameter order in u_discs
and v_discs.

If there are no discontinuities on the geometry then n_u_discs and/or
n_v_discs will be returned as zero.
