Massive layout/Card Class Change

Layout modified to intended layout
Card class integrated (mostly) - modification needed
Functionality temporarily suspended - will need to be added back in,
primarily through modifying calc.java class
Added snapping effect back in
Minor Changes

-Made answer card visible
-Readded setters and getters in class numbercard
answer card drag and snap
one click set back on cards in workspace
Merge branch 'Roland-Layout' into develop
Images Added

Dillon has created some preliminary images that we can use!
I have added strings containing the location of the image.
The group assigned to integrating the images will need to write the
paintcomponent function to paint these images using the given string.
The image is located in the package/folder "images"
Set the backgrounds for the panels. Still need an image for the workspace panel. Panels need to be formatted so that text is not obscured.
Slight Image/Layout Change

Changed Card Bar Image
Very slight modifications to code and layout to enhance aesthetics
Slight Image/Layout Change 2

Changed the side bar image; made slight layout changes to enhance
aesthetic presentation
Slight Image/Layout Change 3

Added an image for Workspace; wrote code to incorporate image
*Note - snapping in workspace may need to be moved if titled border is
removed
Slight Image/Layout Change 4

Operation Bar Image and Layout changed to enhance aesthetics
Slight Image/Layout Change 5

Last change for panels for the "theme" that I made.
Changed cardholder
Also changed the border for workspace, which needs to be there in order
for cards to snap to correct location.  Otherwise snapping will need to
be corrected
Added merging of cards to create an answer card
Border Change

I thickened borders so that cards could be positioned correctly
I also commented out the switch statement and used ifs because my
compiler was complaining
Switch if statements

used if statements instead of switch statements
Dont' know why it didnt' update with the others...
new classpath
Revert "new classpath"

This reverts commit 216e870ce270dd37f10cb3f0bdc14f4fb323296e.
Operation Cards Regen

Fixed so that when cards morph, operation card regens for use in next
expression
Added Java SDK ( i think...)

my program wouldn't work but then when I added this back it did... not
sure if anyone else had the problem... perhaps it was because the 1.6
SDK got deleted somewhere down the line
