 Boilerplate code is annoying and sometimes there can be a lot of it working with [Raspberry Pi GPIO](https://pypi.python.org/pypi/RPi.GPIO). I got tired of setting the board mode and declaring GPIO channels in every script so I made a library that uses a config file instead. In addition to getting rid of the boilerplate, **Pi-Pin-Manager** has the added benefit of pulling the configuration out of the code. This means you can modify any pin's behavior without ever touching a Python file or having to redeploy your program.

 When creating an instance of `pi_pin_manager.PinManager`, there are two ways you can supply pin configuration information: A config file, written in [YAML](http://en.wikipedia.org/wiki/YAML) or a dictionary. If a pin is not defined at this step it will not be available to the `PinManager`.

 If an `event` and `handler` have been defined for a pin in the config file, then you must also provide a class that contains the callbacks to execute. Each method you add to this class should match the name of a `handler` value. Based on the example code below, `handler: do_something` is expected in the config file `path/to/config/file.yml`.
