/// Unity provides an great UI system which includes a Button component which can call functions on objects when it is pressed.
/// A limitation is that you cannot determine who has pressed the button which can be useful in multiplayer environments.
/// For this case we provide the Humanoid Button.
/// When a Humanoid Button is pressed, a function can be called which takes a HumanoidControl parameter
/// representing the humanoid who pressed the button. This parameter can be used to make the functionality dependent on who pressed the button.
