Hey ladies and gents,

So this is my first project, thank you to the boarders that helped me get started. It's a program designed to give a list of usable musical chords to play once the user has selected a root note and a mode.

If anybody is well versed enough in musical theory to confirm that the program is accurate, that feedback would be awesome. Otherwise, enjoy. 

--This program will (hopefully) be able to randomly generate, or let the user select a key and mode.  
--then let the user know what chords to play in that mode 
--Thanks to Irv at open Euphoria for debugging help
