/// This method is for comparing the speed of the ArrayCoreMap family and

/// for both a CoreLabel (can be swapped out for an ArrayCoreMap) and a
/// HashMap. Switching the order of testing (CoreLabel first or second) shows
/// that there's a slight advantage to the second loop, especially noticeable
/// for small i - this is due to some background java funky-ness, so we now
/// run 50% each way.
