/**
* The scope object.
*
* A stateful object shared between a group of clients connected to the same context path. Scopes are arranged in hierarchical way,
* so its possible for a scope to have a parent and children scopes. If a client connects to a scope then they are also connected to its parent scope.
* The scope object is used to access resources, shared object, streams, etc. Scope is a general option for grouping things in an application.
*
* The following are all names for scopes: application, room, place, lobby.
