Input is not robust (Command Line Interface)

[bebenlebricolo]

Use case :
-> Send random stuff to executable, wait for it...... crash!

$ FreeMyCode ùaekmkf anefjia cjdqsico

Parser should be tuned to avoid such crashes
Crash occurs :

• Input is filled with crap (parser)
• All arguments are not filled (3 of them are filled )
• logger tries to access to logfile (which is empty at this time)
  -> parser should have told FreeMyCode to abort execution before.

Possible solution :
Check inputs BEFORE trying to access it.

• Inputs are already checked, but in the FreeMyCode.cpp scope, not in the parser's scope
  -> Parser should return an error (false) as soon as it detects an error in CLI
