Now placing access points throws exception if there is more access points than empty spaces.
Added basic gui and event handling.
Added panel that displays map after it is loaded from file. Still needed adding tabs for second map. Also it only displays map without accessPoints placed so far
Many changes including gui and calculation signal power.
