Efficient Tiny State Machine using object callbacks. Implemented in many languages.

Implement a bare bones state machine in many languages. This library aim to be simple as possible and support only basic features:

• states on object (owner)
• optional enter/exit methods
• virtual state user methods
• is in
• unrestricted transitions
• no runtime allocation

• c++
• c#
• go
• java
• lua
• node
• python
• ruby
• rust

For small and simple state machine needs. Source code for each language is very small, easy to copy/paste...
Also because it's funny to see how a little bit of code can be different from language to language.

Depend on the language, etsm is designed to be a one file dropper in your project. But a package might also be available.
