A set of helper functions to make it easy to add, or modify, keypads to a graph.

The options available are the basic options for any component (ie. :scale, :translate, etc). Keypad also take a second options of :buttons. The :buttons option takes in the options from the core buttons component and applies that to each button in the keypad.

The keypad events correspond to the keys pressed. All numbered keys send a tuple with :keypad and the number that was pressed (ie. {:keypad, 1}. Asterisk and pound send {:keypad, :asterisk} and {:keypad, :pound} respectively.
