Restarts Bluetooth Module on Mac OS X. You can use the script as shortcut to restart Bluetooth on demand or you can use it with "SleepWatcher" to automatically restart Bluetooth on wakeup (See README.md). I created it, because my Logitech Bluetooth Mouse doesn't stay connected after sleep-mode, so i had to manually re-pair my mouse.

Eliminating left recursion from example
To begin with, the wikipedia left recursion algorithm is much eaiser to read: http://en.wikipedia.org/wiki/Left_recursion#Removing_indirect_left_recursion
So, we have the non-terminals A_1, and A_2:
A_1 -> A_2a | b
A_2 -> A_1c | ab
let's step through the algorithm:
i = 1
j = 1
