Added launch files for the demo and made a little change to theargument checker to make them work.
Added linesensor to the behavior class.
Added maps and menus in scoutsim.
Menu options for about, quit, clear, and viewing different maps.
Behaviours now have names!
New behavior implementation that uses a list of behaviors to command multiple scouts with multiple behaviors.
