WIP towards #665
In this PR we added an optional flag to AND operator constructor to define that the last clause is to be considered a NOT clause. For instance
AND(A, B, C)is considered asA AND B AND (NOT C).Regarding #665 , we are still missing allowing
ANDNOTas a token (or a valid metta tag) in a PM query. I.e. after this PR we have the required functionality in the AND operator but we still don't have means to make a query with ANDNOT in the pattern matching agent. This will be implemented in a follow up PR.
