Changes:
	-The camera is adjusted so that the view will fit to any size of the
screen regardless of the screen revolution. 
	-Camera can no longer move out of the map.
	A wrapper class (Myrunner.java) for the controllable character
“runner” is made. This class is a subclass for actor.
	-A wrapper class (TiledMapWrapper.java) for the tiled map is made thus
it is easier to access the properties of the map.
	-InputAnonymizer.java is renamed as RunnerInputAnonymizer.java to
specifically translate the input for runner class. MazeInputAnonymizer,
DialogInputAnonymizer will be added later. I am doing this because the
input might be translated to different output according to which kind of
game the player is in. Like Z is attack in runner game but Z is dash in
maze. The RunnerInputAnonymizer can be easily re-write to another
inputAnonymizer once the outline is there.

Things still working on:
	-Using Screen class
http://libgdx.badlogicgames.com/nightlies/docs/api/com/badlogic/gdx/Screen.html
to switch before different scene.  A game starting screen will be added
in so that the player will be able to click on the screen to start the
game instead of starting the runner game at the beginning of the
application. 
	-Continue to implement the RunnerInputAnonymizer.
	-Trying to figure out how the tile map collision layer works. Maybe
making a demo application.
