BREAKING CHANGE: SchemaBuilder::build() and buildAST() and constructor
removed the typedecorator, as not needed anymore as library can now resolve
union and interfaces from generated schemas.
* Generalizes building a value from an AST, since "scalar" could be misleading, and supporting variable values within custom scalar literals can be valuable.
* Replaces isNullish with isInvalid since `null` is a meaningful value as a result of literal parsing.
* Provide reasonable default version of 'parseLiteral'

This proposes replacing leading comment blocks as descriptions in the schema definition language with leading strings (typically block strings).
While I think there is some reduced ergonomics of using a string literal instead of a comment to write descriptions (unless perhaps you are accustomed to Python or Clojure), there are some compelling advantages:
* Descriptions are first-class in the AST of the schema definition language.
* Comments can remain "ignored" characters.
* No ambiguity between commented out regions and descriptions.
Specific to this reference implementation, since this is a breaking change and comment descriptions in the experimental SDL have fairly wide usage, I've left the comment description implementation intact and allow it to be enabled via an option. This should help with allowing upgrading with minimal impact on existing codebases and aid in automated transforms.
BREAKING CHANGE: This does not parse descriptions from comments by default anymore and the value of description in Nodes changed from string to StringValueNode
This RFC adds a new form of `StringValue`, the multi-line string, similar to that found in Python and Scala.
A multi-line string starts and ends with a triple-quote:
```
"""This is a triple-quoted string
and it can contain multiple lines"""
```
Multi-line strings are useful for typing literal bodies of text where new lines should be interpretted literally. In fact, the only escape sequence used is `\"""` and `\` is otherwise allowed unescaped. This is beneficial when writing documentation within strings which may reference the back-slash often:
```
"""
In a multi-line string \n and C:\\ are unescaped.
"""
```
The primary value of multi-line strings are to write long-form input directly in query text, in tools like GraphiQL, and as a prerequisite to another pending RFC to allow docstring style documentation in the Schema Definition Language.

This revert #202 (commit 9d37f4c) because trying to parse PSR-7 request
was a mistake. The whole point of PSR-7 is to allow for interoperability
and be able to use specialized libs for body parsing (amongst many other
things). Trying to parse ourselves would be opening a can of worm if/when
other content types have to be supported. It is more correct and future
safe to require that the body is parsed before being passed to GraphQL.
Because PSR-7 specification only specify that `getParsedBody()` **may**
return the parsed body for `application/json`, we cannot assume that it
is always the case. So if the value returned parsed body is an empty array,
it means we should try to parse it ourselves (`null` would mean no body at
all according to spec).
With this modification we try to used given parsed body, but fallback on
trying to parse the body if necessary. This leave the door open to custom
implementation of parsing if needed, while making it easier to use out of
the box.
specification.
The framework currently coerces query variables similar to the way it
treats output values, which means it attempts to coerce the value into
the field's corresponding data type regardless of the received value.
According to items 3f and 3g in section 6.1.2
(http://facebook.github.io/graphql/#sec-Validating-Requests) of
Facebook's GraphQL specification query variables should be coerced
according to their type's input coercion rules laid out in section
3.1.1 (http://facebook.github.io/graphql/#sec-Scalars). If the value
can not be coerced into the correct type according the the input
coercion rules for the type a query error should be thrown. This
ensures that client provided query variables were of the correct format
and will be a valid format and type by the time they are passed into an
implementing resolver.
This patch fixes the above issue by updating the way query variables
are sanitized during the process of parsing the query. It directly
follows the rules for scalar input coercion laid out by the
specification and throws query errors when a value that cannot be
coerced to the correct type is given. Tests for isValidPHPValue will
also be updated to ensure that it is doing the correct type checks on
Values::isValidPHPValue for the given type and value provided. A new
test case will also be added to test Values::getVariableValues and make
sure it is also enforcing the scalar input coercion rules and throwing
errors for invalid values.
