<wtf/transformer: First draft of transformers>

To be continued
<wtf/wtf: Remove dead code>

not used anymore.
<wtf/mp: Remove dead code>

This dead code was due to the old style of import.
<wtf/ mp_set: Remove dead code>

This code was also due to the old kind of import we used.
<wtf/transformer: Adds the matchor to transformer module>

By doing this, we are able to use the matcher word cannocalization

before something like a comma.
Merge branch 'features/wtf/word_transformers' of github.com:qubs/quarkslab_test into features/wtf/word_transformers
