+// CLASS DESCRIPTION (MTesselationParams)
+//
+// This class provides control over the tesselation operation.
+// This class is meant to be used in conjunction with the tesselate
+// method of MFnNurbsSurface.
+// 
+// The tesselation operation works by building an initial mesh and then
+// refining that mesh until certain subdivision criteria are met. This class
+// provides control over both the method of construction of the initial
+// mesh and also the criteria for subsequent refinement.
+// The initial tesselation is specified by the polygon output type, and the
+// isoparm type. The secondary tesselation (or subdivision) is specified by
+// the tesselation format.
