 Your challenge is to calculate the exit point of a laser shot into one of the open doors.
 You need to provide the room it will be exiting through along with the orientation.
 The definition file will be provided through command line parameters.
+
+The Mirrors
+There are two types of mirrors that may appear in definition file, 2-way and 1-way.
+A 2-way mirror has a reflective surface on both sides.  So no matter which side a beam strikes the mirror on, it will reflect off at a 90 degree angle away from the mirror.
+A 1-way mirror has a reflective surface on one side.  When a laser beam strikes the reflective side of the mirror, it will reflect off at a 90 degree angle away from the mirror.  If the laser beam strikes the non-reflective side, it will pass through the room as if the mirror was not there.
+
+The Definition File
+The input file will be an ASCII text file with the following format:
+The board size
+-1
+Mirror placements
+-1
+Laser entry room
+-1
+Description of each section of the definition file:
+�	The board size is provided in X,Y coordinates.
+�	The mirror placement will be in X,Y coordinates indicating which room the mirror is located.  It will be followed by an R or L indicating the direction the mirror is leaning (R for Right and L for Left).  That will be followed by an R or L indicating the side of the mirror that is reflective if it�s a 1-way mirror (R for Right Side or L for Left Side) or nothing if both sides are reflective and it�s a 2-way mirror.
+�	The laser entry room is provided in X,Y coordinates followed by an H or V (H for Horizontal or V for Vertical) to indicated the laser orientation.

+At a minimum, your application should print the following to the screen:
+1.	The dimensions of the board
