Refactored correlograms parameters.
[WIP] Refactoring in progress...
Removed test_userpref.py that cannot work easily with the refactored version.
More refactoring with utils.
Further refactoring with logging.
Further refactoring with the settings module.
Fixed bug where some datasets could not be opened as they had a CLUINFO file instead of a ACLUINFO one. Now the program can read both prior to the conversion.
