…shtein distance. Added new test cases that spotted the bug in the implementation. This fixes larsga#268, along with larsga#239 and larsga#244.

I spotted a mistake in the implementation of the Levenshtein.distance and WeightLevenshtein.distance methods. The errors described in #268, #239 and #244 comes from using the wrong indexing in the "matrix" array. Also, the value returned in both methods does not return the correct cell, i.e. last value in the "matrix" 1-dimensional array (by analogy the bottom right cell of the two-dimensional memoization matrix).
By the way, thank you for the tremendous amount of work input into Duke.
