Please @hwchase17 kindly help review.

Thanks!

Instructions:
First, generate cypher then convert it to NebulaGraph Cypher dialect(rather than standard):
1. it requires explicit label specification when referring to node properties: v.`Foo`.name
2. it uses double equals sign for comparison: `==` rather than `=`
1. it requires explicit label specification only when referring to node properties: v.`Foo`.name
2. note explicit label specification is not needed for edge properties, so it's e.name instead of e.`Bar`.name
3. it uses double equals sign for comparison: `==` rather than `=`
For instance:
```diff
< MATCH (p:person)-[:directed]->(m:movie) WHERE m.name = 'The Godfather II'
< RETURN p.name;
< MATCH (p:person)-[e:directed]->(m:movie) WHERE m.name = 'The Godfather II'
< RETURN p.name, e.year, m.name;
---
> MATCH (p:`person`)-[:directed]->(m:`movie`) WHERE m.`movie`.`name` == 'The Godfather II'
> RETURN p.`person`.`name`;
> MATCH (p:`person`)-[e:directed]->(m:`movie`) WHERE m.`movie`.`name` == 'The Godfather II'
> RETURN p.`person`.`name`, e.year, m.`movie`.`name`;
```\n"""
