Pierrick Martin / ctools

"fit" is more appropriate for the tool as the tool itself is not refitting (it's a "refit" of a ctlike result).

Added ctool::require_inobs_nocube() method that throws an exception if a counts cube has been specified as inobs parameter. This method is then used by ctbin, ctexpcube, ctpsfcube and ctbkgcube.

…rk for absolute imports that are used as standard in Python 3. Also always exist with sys.exit() so that errors are correctly catched by Jenkins.

Add __version__ variable to ctools Python module.

Rename __init__.py file into __init__.py.in, add version number, and __init__.py creation instruction into configure.ac.

…served events in ctlike.

… ctcubemask for this purpose

…ontribution is expected.
