StateMechinic is a hierarchical state machine library. It supports data attached to states, data attached to events, entry/exit/transition handlers, child state machines, and more.

StateMechinic has not yet been released. Check back soon!

First, create your state machine. It's a good idea to give it a name: this isn't used internally, but is very useful for debugging.

var stateMachine = new StateMachine("Telephone Call");

Next, create your states and events. As before, it's useful for debugging purposes to give them names.

var stateOffHook = stateMachine.CreateState("Off Hook");

You'll notice that this approach differs from other state machine libraries: states and events are instances rather than enum values. This has a few advantages, as we'll see later.
