Add bubblesort funtion for lane length filterring. Cleared few bugs on
slope comparing. Assigned static frame resolution and stretched image to
achieve fullscreen view.
Add frame rate display. Applied equalizer to all the modes. One problem
remaining is that cannot find a proper way to set check box invisible at
first launch.
Extended the detected lines to infinit. Failed attempts shows the kalman
filter in Java is not available and jni part is useless in this
situation.
Caculate the cross point of 2 lanes as vanish point.
