"""A simple plugin to serve as an example

This is an extremely minimal Kaylee plugin to serve as an example for
developing more complex plugins.  It takes a single configuration
option, "phrase", which is a sentence to be recognized.  Once this is
heard, the plugin prints "Simple plugin says: [phrase]".
