Calling Queries

/*
The Arguments is essentially the parameters for the TigerGraph query.
For example, consider I wrote a Query called "findPhones" which returns all the phones
belonging to a person.

findPhones(Vertex<Person> person)

Here is how I would call it:
*/

Vertex source = Vertex("Person", "1");
Map result = await client.callQuery("findPhones", {"person": source.id});

/*
When inputting a Vertex for a paramater, we can just include the id of the vertex instead of 
passing in the whole vertex object */

/*
If we have a Set as a paramater for teh query, we can simply pass in a list for it.
For example, suppose I had a query called "findCommonFriends" which takes in a set of friends
and returns everyone who is friends with all of them

findCommonFriends(Set<Vertex<Person>> people)

Here is how I would call it:
*/

Vertex v1 = Vertex("Person", "1");
Vertex v2 = Vertex("Person", "67");
Vertex v3 = Vertex("Person", "89");

Map result = await client.callQuery("findCommonFriends", {"people": [v1.id, v2.id, v3.id]});

/*
Furthermore, the JSON objects that are passed will automatically be encoded as Strings
