done for the day 10/22/14

Forgot to commit last night - most of the changes where made then.
* 'Finished' (functioning) preview panel!!!!! Now onto the list ctrl
(table).
* Changed naming scheme (inspired by Kivy, my design needed to change:
there were issues with importing), packages are camelCase, objects are
Pascal (CamelCase).
* Created a class in myClasses, MyTesting, for testing; changed every
module thus far to use it (were necessary - all but gui.dialog.myText:
no need there...).  Going to work on the wiki now.....
