Use COMPARE token for defining comparison operators in PartialComparisonExpression rule

[1sand0s]

Using a COMPARE token to define the list of possible comparison operators before their usage in the oC_PartialComparisonExpression production rule makes it possible to easily identify which operator was used in the parsed Cypher query (by fetching the terminal node COMPARE).

Thanks again for your intent to contribute to openCypher.
