/// <summary>
/// Component that is an endless mesh. You don't need to worry about the 65k limit when adding meshes. It is like a List of combined meshes. Internally it manages
/// a collection of CombinedMeshes that are added and deleted as necessary. 
/// 
/// Note that this implementation does
/// not attempt to split meshes. Each mesh is added to one of the internal meshes as an atomic unit.
/// 
/// This class is a Component. It must be added to a GameObject to use it. It is a wrapper for MB2_Multi_meshCombiner which contains the same functionality but is not a component
/// so it can be instantiated like a normal class.
