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.
