main.lua

--[[

This is the main.lua file. It executes first and in this demo
is sole purpose is to set some initial visual settings and
then you execute our game or menu scene via composer.

Composer is the official scene (screen) creation and management
library in Corona SDK. This library provides developers with an
easy way to create and transition between individual scenes.
