Added functions pow, dup, and drop pow pulls two numbers from the stack and raises the second pulled to the first pulled. This was implemented using a exp function I wrote previously and a log function I just wrote. If an integer power is requestion, it uses the standard O(log(n)) algorithm... This function can be called using '**' drop drops the top value of the stack and dup duplicates it... I also modified the make file so that it supports header file dependencies
