/**
* glyr_levenshtein_strcmp:
* @string: first string to compare
* @other: second string to compare
*
* Computes the levenshtein distance betwenn @string and @other.
* See Also: http://de.wikipedia.org/wiki/Levenshtein-Distanz
*
* In very simple words this means: glyr_levenshtein_strcmp() checks if two
* string are 'similar', the similarity is returned as int from
* 0 (== total match) to MAX(strlen(string),strlen(other))
*
* This is fully UTF-8 aware and calls g_utf8_normalize() beforehand.
*
* Example:
* <note>
* <para>
* Equilibrium <=> Aqquilibrim
* will return 3 since:
* Equilibrium -> Aquilibrium // one Edit: 'E' -> 'A'
*
* Aquilibrium -> Aquilibrim // one Delete: 'u' -> ''
*
* Aquilibrim -> Aqquilibrim // one Insert: '' -> 'q'
*
* </para>
* </note>
*
* Returns: the levenshtein distance (number of Edits, Deletes and Inserts needed to turn string to other)

/**
* glyr_levenshtein_strnormcmp:
* @string: first string to compare
* @other: second string to compare
*
* Same as levenshtein_strcmp, but tries to normalize the two strings as
* best as it can (includes strdown, stripping html,
* utf8 normalization, stripping stuff like (CD 1)
* and Clapton, Eric -> Eric Clapton
*
* For very small strings the function may return very high values in order
* to prevent accidental matches. See below.
*
* internally glyr_levenshtein_strcmp() is used, so this is UTF-8 aware as well.
*
* Example:
* <note>
* <para>
* Adios <=> Weiß or 19 <=> 21 return 4 or 2 for glyr_levenshtein_strcmp()
* (and may pass a max threshold of e.g. 4),
* but a lot higher value with glyr_levenshtein_strnormcmp()
* </para>
* </note>
*
* Returns: the levenshtein distance
