Comments and Nulls

[garfieldmoore]

I have extracted a schema from an API. However, graphdoc fails to parse for 3 reasons;

1. there is a "\uFFD" character
2. The schema had multi-line comments i.e. see below for example from the schema

"""
The Date scalar type represents a year, month and day in accordance with the
ISO-8601 standard.
"""
scalar Date

3. there are nulls

For the first issue i converted to utf-8
then I replaced all occurences of null with "null"
and finally I removed the comments

This worked and graphdoc produces the documentation but it would be great the tool could parse this schema.

I used the npm package get-graphql-schema to produce the schema so unsure if some of these issues are due to that package producing an invalid schema files.
