TITLE: RMan Shader SOP

RMan Shader allows you to attach different RenderMan shaders to different groups
of primitives.

There are spaces in a single RIShader operation to assign up to 6 different
RenderMan shaders to 6 (possibly different) groups of primitives.  If
that is not adequate then users can string a sequence of RIShader operations
together to assign more than 6 different shaders.  Note that you can override a
shader assignment within a sequence of RIShader operations.

Parameters:

    Group       - Specify the groups in question
    Shader Name - Name of RenderMan Shader to assign to the said group(s)
