DataMapper plugin that adds state machine functionality to your models.
== Why is this plugin useful?
Your DataMapper resource might benefit from a state machine if it:
* has different "modes" of operation
* has discrete behaviors
* especially if the behaviors are mutually exclusive
And you want a clean, high-level way of describing these modes / behaviors
and how the resource moves between them. This plugin allows you to
declaratively describe the states and transitions involved.
