44dc80bb37 Replace substitution function with a map
It makes using variables with queries more approachable, but some work
still has to be done.
- The type `Subs` should be renamed and moved out of `Schema`, together with
`AST.Core.Value` probably.
- Some kind of conversion should be possible from a user-defined input
type T to the Value. So the final HashMap should have a type like
`HashMap name a`, where a is an instance of a potential typeclass
InputType.

78ee76f9d5 Define schema AST.
Large parts of the schema aren't exported publically. They will be made
public during writing the parser.

Fixes #6.

4c0d226030 Move Transform to Language.GraphQL.Execute
Language.GraphQL.AST.Transform is an internal module. Even though it
works with the AST, it is a part of the execution process, it translates
the original parser tree into a simpler one, so the executor has less
work to do. Language.GraphQL.AST should contain only the parser and be
independent from other packages, so it can be used on its own.

73fc334bf8 Move related modules to Language.GraphQL.AST
Fixes #18.

- `Language.GraphQL.Encoder` moved to `Language.GraphQL.AST.Encoder`.
- `Language.GraphQL.Parser` moved to `Language.GraphQL.AST.Parser`.
- `Language.GraphQL.Lexer` moved to `Language.GraphQL.AST.Lexer`.
- All `Language.GraphQL.AST.Value` data constructor prefixes were removed. The
  module should be imported qualified.
- All `Language.GraphQL.AST.Core.Value` data constructor prefixes were removed.
  The module should be imported qualified.
- `Language.GraphQL.AST.Transform` is now isn't exposed publically anymore.

417ff5da7d Propagate Maybe in the transform tree
Since the transform tree can already find some errors, it may fail here
and there. Almost all functions return a Maybe to signalize an error.
Will be replaced with an Either of course.

63d4de485d Deprecate enum, enumA, wrappedEnum, wrappedEnumA
These functions are from Language.GraphQL.Schema.
There are actually only two generic types in GraphQL: Scalars and objects.
Enum is a scalar value. According to the specification enums may be
serailized to strings. And in the current implementation they used
untyped strings anyway, so there is no point to have differently named
functions with the same implementation as their scalar counterparts.

22313d05df Deprecate Language.GraphQL.Execute.Schema
It is not a schema (at least not a complete one), but a resolver list,
and the resolvers should be provided by the user separately, because the
schema can originate from a GraphQL document. Schema name should be free
to provide a data type for the real schema later.

61879fb124 Constrain the resolvers with MonadIO
This replaces the most usages of MonadPlus, which is not appropriate for
the resolvers, since a resolver is unambiguously chosen by the name (no
need for 'mplus'), and the resolvers are often doing IO.

Now the errors in the resolvers can be handled and 3 tests throwing

nullable and non-nullable values.
