Modèle BDD + Couche Service pour checkWord
Completed service layer +
modified exception handling (to be properly returned by WS) +
created WS layer
AddWord now allows to save words even if language did not exist previously
bootstrap once again and created command line interface

following TDD methodology: create test, fulfill them asap, refactor
Need yet to refactor on the whole class :)...

TODO on the CLI class:
- extract vars and process from CLI class to a new service class
- plenty of strings to put to properties for localization (output to user: description of methods, feedback on the treatment)
Refactoring: use of a ProcessData pojo to manage the lists of words (processed, discarded, added)
Cli:
added Exception Handling,
started Service Layer. Reads files
Updated data model
Started client to WS

WordRepo:
modified response objects to provide proper json response
Detect language
add properties file
completed treatment (call addWord).

Finalise project before submitting.

checked warnings with sonarqube.

Final tests with French and spanish texts
found bugs and provided workarounds for some of them. (see todo & fixme)
