## Patch class

  A Patch is a parametric modeling surface, similar to NurbsSurface, it's also defined by two  PatchDirection, the U and V.  But difference between Patch and NurbsSurface is that the PatchDirection curve  can be one of PatchDirectionType.BEZIER, PatchDirectionType.QUADRATIC_BEZIER, PatchDirectionType.BASIS_SPLINE, PatchDirectionType.CARDINAL_SPLINE and PatchDirectionType.LINEAR
