public interface IGlobals

Globals, are cluster-wide global values that are kept in synch between the Lobby and all Game Nodes
They can be initialized from the main Lobby's Extension init() method and/or updated at a later time.

Globals are stored as a Map of Serializable values indexed by String keys. They are meant to provide cluster-wide settings or application state, but they are not meant for real-time updates, meaning that very frequent updates are not allowed (i.e. frequency < 1sec).

NOTE: the update mechanism works only when setting calling the set() method from the Lobby side.
