Automatic array handling

[yeegor]

Overview

Currently, when an array-like field is getting created, it is necessary to pass an additional argument to the creation process:

const people = new Query('people', true)
    .addField('friends', true)
    .addField(new Field('parents', true)
        .addField('gender')
        .addField('age')
    );

const result = await client.post(people);

result[0].friends[0];
result[0].parents[0].gender;
result[0].parents[0].age;

Expected behavior

In the ideal world, this is handled completely automatically.

Brief mockup:

1. Use GraphQL type introspection functionality to generate the schema of TS types locally.
2. When building the type - either during the field generation process or query fetching, use the generated schema to determine whether the field is an array or not.
