Added the PATH searching algorithm we talked about at the last meeting with Ciaraldi. It will find the location of our program
and search the PATH for that location. If found, it will search all remaining elements for the requested program. If the location
is not found on the PATH, then it will search the entire PATH for the requested program. If found, it returns the absolute path
to the program. If not, err.
