Macro input_map 

macro_rules! input_map {
    () => { ... };
    ( $( $t: tt )* ) => { ... };
}

Outputs an input with the inputed binds.

The input is structured by a list of (Action, bind, bind, ..). An action is pressed if any of its binds are pressed.

Binds are described as either [InputCode, InputCode, ..] or InputCode. A bind is pressed if all its InputCodes are pressed.
