// contains filtered or unexported fields
}
```

Context is the object which allows to calculate the Levenshtein distance with Distance() method. It is needed to ensure 0 memory allocations.

Distance calculates the Levenshtein distance between two strings which is defined as the minimum number of edits needed to transform one string into the other, with the allowable edit operations being insertion, deletion, or substitution of a single character http://en.wikipedia.org/wiki/Levenshtein_distance

This implementation is optimized to use O(min(m,n)) space. It is based on the optimized C version found here: http://en.wikibooks.org/wiki/Algorithm_implementation/Strings/Levenshtein_distance#C
