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).
provide test files
tested with client and server started
