/*
This snippet is to demonstrate how to write to a matrix channel
in modo from an eval modifier. This is the correct way to write
to a matrix. This does assume that you have set the matrix channel
you want to drive as a channel for the modifier, using something like:
eval.AddChan(item_loc, LXsICHAN_XFRMCORE_WPOSMATRIX, LXfECHAN_WRITE);
in your modifier constructor. This method will drive the matrix
channel directly, so instead of using the local channels to calculate
the world SRT, it'll use the values the modifier provides it with.

    Surface Force
    
    This example plugin for modo 701, shows how to create a surface force in
    Python. The force will read a mesh, get the closest position on that mesh
    and find the normal at that position. A force will be created along the
    normal vector of the surface. The result is a force that pushes particles
