|Computes the [https://en.wikipedia.org/wiki/Damerau%E2%80%93Levenshtein_distance Damerau-Levenshtein Distance] for two strings and returns a double value ({{Code|0.0}} - {{Code|1.0}}), which represents the distance. The value distance is computed as follows:<br/>
* <code>1.0 - distance / max(length of strings)</code>
* <code>1.0</code> is returned if the strings are equal; <code>0.0</code> is returned if the strings are too different.
