 4 Portal Strategy 
 * 1) Wait for the lighting to shoot once then quickly grab the cube, bring it back to the button, then proceed to the next area.
 * 2) Place a blue portal on the side wall ahead, parallel to the first cube. (Middle row, third column)
 * 3) Place an orange portal on the floor of the pit.
 * 4) After the lightning has finished, fall through the orange portal and you should hit the cube off of its pedestal as you fly by.
 * 5) Fall through the orange portal again, but this time aim a bit off center so that you can land on the center island and quickly run to grab the second cube and jump off.
 * 6) After both cubes are placed on the buttons, moving back towards the entrance will make the center wall panel come out at 45 degrees.
 * 7) Shoot a blue portal at the center of the ceiling.
 * 8) After the lightning has finished, fall through the orange portal and while falling, shoot a blue portal onto the 45 degree ramp.
 * 9) If you timed it correctly you will have made it to the opposite end of the room and will be able to proceed to the exit.
