An binding to an event that is only run once

@Michael.Kessler

The idea behind this code is that we are generating an event table that we push and then later clean up.

@Michael.Kessler

def singleShotBind(self, eventName, callback):
    """Create a bind that will automatically clean itself up after the first successful run.

    eventName: The event to bind to.
    callback: A runnable that takes the event object.  Returning True from this function will
              cause the cleanup to occur.  Returning False will keep the binding around.​
              If an unhandled exception occurs in the callback, the binding will be torn down.
