-- manages "stages" with a stack interface
-- stage is Lua module with callbacks (load, update, draw, keypress...)
-- only single stage is active, one on top of the stack
-- after push and pop operation another stage takes over the callbacks
-- example stack: os > main_menu > level_selection > game_play > overlay_menu
-- example usage:
--   local stagestack = require'stagestack'
--   stagestack.push(require'main_menu')
