update
moved todo list to the github wiki page
Internal restructure of code

1. Move example code to examples/ directory
2. Add a function registry and look-up so that you specify the example code you
want to run from the command-line.  The usage is now:
    test <example-name>

E.g.
    test scale
    test cv

To see all possible example names, look in main.capp
add forgotten example file
