object mergeInPredicates extends Rewriter with Product with Serializable

Merges multiple IN predicates into one.

Examples: MATCH (n) WHERE n.prop IN [1,2,3] AND [2,3,4] RETURN n.prop

> MATCH (n) WHERE n.prop IN [2,3]

MATCH (n) WHERE n.prop IN [1,2,3] OR [2,3,4] RETURN n.prop

> MATCH (n) WHERE n.prop IN [1,2,3,4]

MATCH (n) WHERE n.prop IN [1,2,3] AND [4,5,6] RETURN n.prop

> MATCH (n) WHERE FALSE

NOTE: this rewriter must be applied before auto parameterization, since after that we are just dealing with opaque parameters.
