MPSBuilder<T> class

MPSBuilder allows you to subscribe to multiple MinPubSub topics.

GraphX has a global mts object that you can use to easily publish data or events to topics.

This widget listens to the topics list and rebuilds when an event is dispatched in any of them.

You can publish without parameters (ems.emit(topic)) or with a single parameter ems.emit1(topic, value).

Experimental! "MPS" is discouraged to use in GraphX. Use ValueNotifier or other Listenable objects instead to create the communication.
