    Diagnostic values (like total KE/ total enstrophy/ mass/ etc)
    are often desired outputs at each time-step. These values
    are easily printed to a txt file using two functions:
    add_diagnostic and write_diagnostics.
    add_diagnostic adds the name and value of a diagnostic into a
    pair of strings which will be written into diagnostics.txt
    which the function write_diagnostics.
    Usage of add_diagnostic is as follows:
    add_diagnostic(name, value, header, line);
    This will add the string, 'name', onto the string, 'header', which
    will be the header of the diagnostics.txt file. The double (or
    int), 'value', will be added onto the string, 'line', which will
    be a row (or line) in the diagnostics.txt file.
    write_diagnostics will write these lines (header and line) into
