Update 2/13/14

- Fixed a glitch where new items in edit mode would retain the number
'3', the default value of the first element when the page loads.
- Removed various comments
- Added comment explanations for anyone who wishes to review my code
and/or way of thinking.

Note: I would very much like to know if there is anything I could be
doing better in this program. If you have some advice, I am all eyes and
ears. :)
Update 2/16/14

I've added various aesthetics and overall functionality.
-Edit, Delete buttons now hide unless a list item is hovered over
-Edit, Delete buttons will now function properly after Save has been
clicked and the user re-enters edit mode. Before the buttons were
showing upon hovering over a list item.
-jQuery numeric() now works properly with dynamically added list items.
User can now only enter numbers where appropriate.
-Modified div to handle overflow of elements so that.
- Changed overall style to a bigger font size and more appealing font.
