Support for Q-gram distance

[EmidioStani]

Hello,

it would be interesting for me to support Q-gram distance.

By looking at the code I see you support those distances from Apache Commons.

I noticed that the java-string-similarity supports such distance (and others), released under MIT license and provided through Maven.

Would it be possible to include it ?

Thanks,

Emidio

Hi Emilio, sure, it makes a lot of sense a nice extension to the function list.

The process should be easy as adding the dependency and wiring the function using the reflection library we developed. This can be done in different ways, see

2c5d286 introduces the function fx:QGramDistance(?n1, ?n2) for computing the QGram Distance between two strings.

The implementation of the algorithm is provided by the java-string-similarity library (I couldn't find the implementation on the apache commons).

579aef7 adds the documentation of the fx:QGramDistance
