}what does this stuff do?
its a wrapper for an list of other ResourceProvider you can simple add new to this with add<CEGUI::DefaultResourceProvider>("default") and access them with get("default")
this is usefull if later more provider chould be added like multible archive provider for more then one archive file
i hope this fits the "Coding Standards in use for CEGUI" ...
