// Mechanical button de-bouncer.
// This can be used in one of three ways.
//
// Beginner : Just call getState() in your loop() function and it'll return true or false
// to match what the button is currently set to. Easy Peasy!
//
// Intermediate : Set a callback function and let this run in the background. When the
// button changes state, true or false, your callback function is called. Again, pretty
// simple.
//
// Pro : Inherit this as a base class and let it become the callback you always dreamed
// of. Remember that in this case, you will probably need to put in a call to hookup().
// But then, you're a pro. So I shouldn't have to tell you that.
