  Usage:

franks42

-- Corona Game SDK example of how to let two bodies circle each other by applying a continuous, attracting force
--
-- The example uses the physics engine, sets gravity to 0, creates two balls separated in the x-direction,
-- with initial speeds in opposite y-direction.
-- Thru an enterFrame event handler, an attracting force is continuously applied to both balls with body:applyForce().
-- The force is normalized over the distance between the two balls.
-- By playing with the initial speed and force factors, you can make the balls spin faster/slower in circles or ellipses
--
-- Save this file as "main.lua" in a project directory and load it in the simulator

-- Color to RGB value table for Lua coding with Corona
-- Color values copied from "http://www.w3.org/TR/SVG/types.html#ColorKeywords"
--
-- Usage for Corona toolkit:
-- add this file "colors-rgb.lua" to your working directory
-- add following directive to any file that will use the colors by name:
-- require "colors-rgb"
--
-- If you need the RGB values for a function list, you can use "colorsRGB.RGB()", like
-- colorsRGB.RGB("chocolate"), which returns the multi value list "210 105 30"
