PrimitiveCentroid v2.008/16/2011
Changed how groups are processed. Previously, a point would be created at the center of the entire group. Now, a point is created for each primitive in that group. Removed the Use Groups toggle and renamed Primitive Groups to Group. Keeping consistent with Houdini, if no groups are chosen, all primitives are used. Removed the HDK dependency. Group names and wildcards are now handled properly by globbing.

Fixed incomplete dopfield, dopoptions and dopnumrecords functions that were accidentally in 1.0. Unlike the hscript equivalents, if these functions fail in any way they throw an exception.
