What changes were proposed in this pull request?

The PR addresses the reversed pattern (u)<-[e]-(v). The parsed result is the same as the pattern (v)-[e]->(u).

Why are the changes needed?

The parser should be able to understand the reverse edge pattern.

Hi @rjurney, now it is ready for review. For me, it looked more like a design choice rather than a feature. It is easy to come up with a workaround, would you elaborate on the use cases and the situation you've experienced?

@rjurney, the PR changes the Parser, but it would be better to rewrite the query string to keep the parser unchanged. I will be opening another PR with that approach.

@rjurney, I am closing the PR as the new PR #717 covers the feature in a better way.
