Searches for a given file in the write and base directories and, if
it exists, returns a path to the file.
This method first looks for the file in the write directory. If it
exists, then a string containing the path "writeDir/fileName" is
returned. Otherwise, it then looks for the file in the base directory
and returns its path if found. If the file exists in neither directory,
the method returns null.
