    \brief Channel-specific interfaces for ParticleChannelMaterialIndex
				 The channel is used to store material index information
				 The channel is a wrap around ParticleChannelInt
				 If the channel is present in the particle container
				 then the index information overrides any material index information
				 in mesh channel with one exception: if index value is -1 then
				 the mesh channel information is kept intact.
