# Luca.SocketManager is an abstraction
# around various websocket services such as
# faye.js, socket.io, now.js, etc.
#
# It provides a common interface for adding
# push / async functionality to Collections,
# Models, and the like, regardless of the
# transport mechanism used.
#
# Simply bind to it, and any message that comes
# across the channel you subscribe to, will be
# bubbled up as a Backbone.Event with the message
# contents as your argument

#### Transport Loading and Configuration
#
# Luca wraps several popular client side socket abstractions
# such as socket.io or faye.js ( more coming soon )
#
# it provides a common interface on top of these and just
# treats them as Backbone.Events which you bind to like you
# would on any other Backbone class
