Make frequency innermost index loop in checkResult
Make frequency innermost index loop in checkResult

Making frequency be the innermost index loop in checkResult allows for
easier outputting of a baseline's spectrum if an error is detected in
one of the baseline's channels.  This will make such outputting easier
to implement in the future, but it is NOT yet implemented.
