find_basename() is a simpler version of basename().
It maintains constness and thus does not require you
to pass in a copy. It is only concerned with finding
the last directory separator in a string and returning
a pointer.
This function was written because Windows does not
have basename(). It is called "find_basename()"
to avoid name collisions and to provide a hint that
it is not quite the same thing as POSIX basename().
