1) Put buttons.js into javascript.js
2) Deleted JavaScript in HTML <img> tags.
3) Assigned ID's to color buttons.
4) Moved javascript.js into UniversalUndies directory
5) Clicking a color should set up a color flag for adding an item to the cart.
6) MouseOn and MouseOff the size buttons causes the button image to change to their respective hover versions. NOTE: We still need a hover image for Small and Medium size buttons.
7) Clicking on size button sets up a size flag for adding an item to the cart. Clicking a button also unselects the other size buttons. Clicking on a clicked size button will cause the button image to revert back to the unselected version.

Next Goals:
1) Possibly create a SizeButton class to clean up code.
2) Use the color and size flags from above to add items to cart. If this works, we can now test out our sorting algorithm and see if that works.
