******************************************************************************
 * This file shows how to write a mental ray shader
 * that uses maya light linking.
 * Although mental ray for maya translates the light linking relationship
 * to the light list of the shader,
 * it can be still useful to modify the shader itself,
 * especially when the shader is used by muliple objects with different light linking.
 *
 * This exmple takes mib_illum_lambert as a starting point
 * (can be found at maya6.5/devkit/mentalray/shaders/public-baseshaders/baselambert.c)
 * and adds code for the light linking.
 * A header file mayaapi.h should be included which can be found at
 * maya6.5/devkit/mentalray/include
 * If Windows is the working environment, 
 * mayabase.lib needs to be linked in addition to shader.lib.
 * Both libraries are located at
 * C:/Program Files/Alias/Maya6.5/devkit/mentalray/lib/nt
