For Windows users: "java UpdateMappers" will, after creating a backup file, update the values of "mapper.txt" in the same directory as the Java class.
You may also add an argument, ala "java UpdateMappers dukemapper.txt", and it will update the specified file. Note that writing the filename extension is necessary in this case.
If the argument points to a directory, it will search through the directory tree specified and convert all files named "mapper.txt" it finds.

It will also detect if the mapper file has already been updated, and inform the user as such.
