Massimiliano Culpo 94bb37c107 concretizer: simplify "fact" method (#21148) ... The "fact" method before was dealing with multiple facts registered per call, which was used when we were emitting grounded rules from knowledge of the problem instance. Now that the encoding is changed we can simplify the method to deal only with a single fact per call. (cherry picked from commit ba42c36f00)		2021-05-21 15:09:04 +02:00
