Added bbox parameter to draw_rectangle function, so we can specify bbox or have function obtain it automatically. Now able to re-use draw_rectangle function.
Modified Point class definiton to enable initialization of values. Added functions to generate and draw polygons. Created Polygon ojbect.
Added in extra invocations of Polygon to create Czech Republic flag. Not a dumbass, so just used red/white/blue. Removed extraneous print statements.
