> The calculation made by the LevenshteinDistance class can often be made
> faster, when the class in initialized with a threshold, and when the distance
> is found to be larger than the threshold. In those cases, it is often not
> necessary to iterate through the whole string, since a lower bound for the
> result can be established after each iteration. If that lower bound is larger
> than the threshold, the method can simply exit early with the same result as
> without this improvement.
> A patch with the proposed change is attached to this issue.
