// You can click on the enabled (ie. blue) actions in the diagram, and view the current state in the "state" tab on the right. 

// For simplicity, the `PROPOSE_NEW_OUTCOME`
// event uses nextOutcome() to assign the
// proposed outcome.
// You can proposedOutcome in the
// customActions object with the following
// 
//  proposedOutcome: function(c, event) {
//    return event.outcome;
