-- love.load() - at the game's start, used to initialise ressources 
-- love.update(dt) - the game loop function, where "dt" stands
--    for the fraction of seconds since the function was called last
-- love.draw() - graphics output loop
-- love.mousepressed(x, y, button) - mouse down event callback function,
--    where x, y the mouse's position, and button the number of the 
--    button pressed. 
-- love.mousereleased(x, y, button) - mouse button release event callback function, 
--    see mousepressed
-- love.keypressed(key) - key press event callback function, where key is either 
--    a character, or any of the constants like "up", "down", "left", "right"
-- love.keyreleased(key) - key release event callback function - see keypressed
-- love.focus(f) - windows focus received/lost event callback function, where f
