API options comparison for elm-gamepad

{-

   As a game developer, I want to allow the player to remap the game controls, to allow them using non-recognised pads and suit their personal comfort.

   As a game developer, I want to access specific gamepad inputs with consistent naming that does not depend on hardware or user preferences.
