Exit and Draw Command
Implemented Template Method

-In the draw method of each shape, it now creates a draw(shapename)
object, which is a template method object
-this gets rid of the duplicated code that was in the draw methods for
the shapes
-also fixed the rectangle drawing bug
basic saving done, working on loading now
forgot to mention that i didnt check if saving worked with redo/undo yet. will check soon
fixed a small bug where a circle must be on the drawpanel before saving to a file. checked undo and redo: both works fine
selecting works but is very basic right now

Basic Shape Selection
fixed merge conflicts
Grouping and Ungrouping Working

-changed the pointset within basic shape to be an arraylist
-changed selecting so when you select shapes after you've already
selected some, it unselects the others
-you can group shapes, it will add a group to the arraylist and remove
the selected shapes
-you can ungroup shapes, it will remove the group from the arraylist and
add the shapes within the group
Merge pull request #20 from andeic/groups

Grouping and Ungrouping Working
fix merge
 changed format of files and did basic outline of load. will finish file handling by tomorrow
loading and saving works. cannot undo a load yet. also, after loading you can still redo, will have to fix that up. will have to find a way to also store history
fixed a small bug where the loading of a file would sometimes be able to undo the last shape that was inputted. reread my code and it says load will not be implemented
