public class JiffleExecutorDemo
extends JiffleDemoBase

Demonstrates the use of JiffleExecutor to run a script.
There are two options for running a Jiffle script...

1. Directly, by getting a JiffleRuntime object from the compiled Jiffle object.
2. Indirectly, by submitting a Jiffle object to a JiffleExecutor.

The advantage of the second method for computationally demanding tasks is that execution is carried out in a separate thread. The caller is informed about completion or failure via JiffleEvents and can track progress using a JiffleProgressListener.
