Removing the entity preprocess from all the code. It was a bad idea to include it.
0.0.6
Allowing an entity preprocess function as parameter in the constructor.
0.0.5
Adding weighted levenshtein algorithm.
0.0.4
Fixed a bug because the entity to search wasn't preprocessed but the rest of indexed entities were.

Fixed a bug with the insertion of similar or equals entities. This fixed bug has increase the algorithm performance a lot.
