Better comments for ContextProvider class
Renamed EditKidsActivity to EditConfigActivity
Added better comments
Removed dead code
Seperated the debug buttons from the rest of the code more cleanly.
added comments
-Implemented ViewHolder pattern to cache KidsList entries and make
scrolling faster and smoother.

-Added "edit" buttons, plus all the back end stuff

-"Add" button isn't in there yet, but the framework is in place to make
it happen now.  Before the list could only display kids, now I should be
able to insert arbitrary list items as needed.
