PublisherChannel( )

A simple publisher-subscriber framework. Methods are bound to the PublisherChannel, and called with the supplied parameters when a channel is notified they belong to. These methods are called at the scope they are bound, which means they are run as if they were a part of the subscribing instance. Thus any number of instances can subscribe to a single PublisherChannel, or even the same one multiple times if desired.

var _channel	= new PublisherChannel()

_channel.add( function( _message ) {
  show_debug_message( _message );
}
_channel.notify( "Hello World!" );
