==== Changes to Fuzziness

To create `Fuzziness` instances, use the `fromString` and `fromEdits` method
instead of the `build` method that used to accept both Strings and numeric
values. Several fuzziness setters on query builders (e.g.
MatchQueryBuilder#fuzziness) now accept only a `Fuzziness`instance instead of
an Object. You should preferably use the available constants (e.g.
Fuzziness.ONE, Fuzziness.AUTO) or build your own instance using the above
mentioned factory methods.

Fuzziness used to be lenient when it comes to parsing arbitrary numeric values
while silently truncating them to one of the three allowed edit distances 0, 1
or 2. This leniency is now removed and the class will throw errors when trying
to construct an instance with another value (e.g. floats like 1.3 used to get
accepted but truncated to 1). You should use one of the allowed values.
