Some questions about suffix_method

[tbazin]

@wangsix : the MO class offers a parameter suffix_method (currently with two recognized values, 'inc' and 'complete'), VMO and FO don't support it. Where is this parameter introduced? Is it specific to the repository or does it appear in an article?

Is there any reason why MO should benefit from it and not FO/ VMO? I am rewriting all three classes to use a unified add_class method, and shall integrate this parameter regarding the suffix links within this generic function in case it's relevant.

The suffix_method is unique to MO and not applicable to either VMO or FO. For FO, the two options for suffix_method will be the same due to symbolic comparison. Since VMO is centroid-bases, there is also no point of having suffix_method in it.

The 'complete' option in suffix_method is a different heuristic of how new data should be added to the oracle and is not documented in papers yet.
