    // NOTE: First line to be analyzed is:
    // Matthew Alan Aberegg 1963  452,627
    // among other things, I need to take this and put it in the format:
    // Aberegg, Matthew Alan 1963 452,627
    // The file i am opening is filled with lines like that one, except some are formatted correctly, some are not.
    // The following (very incomplete) code SHOULD extract the last name, "Aberegg", but it seems to be caught in an
    // infinite loop somewhere. Any help/suggestions for any improvement would be greatly appreciated.
