Adds ORDER BY

[jackboyla]

from grandcypher import GrandCypher
import networkx as nx

host = nx.DiGraph()
host.add_node("a", name="Alice", age=25)
host.add_node("b", name="Bob", age=30)
host.add_node("c", name="Carol", age=25)
host.add_node("d", name="Dave", age=25)

qry = """
MATCH (n)
RETURN n.name 
ORDER BY n.age ASC, n.name DESC
"""
res = GrandCypher(host).run(qry)
# names sorted in descending order where ages are the same

print(res)

# {'n.name': ['Dave', 'Carol', 'Alice', 'Bob']}

also extra test for DISTINCT

Adding ORDER BY requires some slight changes in the order of operations being applied.

Pagination (LIMIT + SKIP) has to wait until all other operations are applied.

Did some refactoring on returns because it was getting pretty big😅

AMAZING stuff, particular kudos for the great inline docs, the thoughtful unittests, and the super helpful error messages when things fail assertions!! THANK YOU!
