TITLE: TriBezier SOP

The TriBezier operation creates a triangular Bezier surface using a user
specified group of points as the control points of the Bezier. The order of the
points is important for creating the surface.  The number of points should be
(order+1)*order/2.  Order 4 requires 10 points, order 3 6 points, and
order 2 (a triangle) 3 points.  Extra points are ignored.

The order of the points should be as follows for an order 4 patch:

~c(
0
|\
1-2
|\|\
3-4-5
|\|\|\
6-7-8-9
~c)

Parameters:
    Group  - This is the points, in order, to be used.
    Order  - This is the order of the resulting patch.                /order
