1.0.0a1

Contains BREAKING changes.

Changelog

• BREAKING: Change how templates work

  Now, template variables have a syntax: ${var} and by default, they are substituted with an equivalent GraphQL object, i.e. strings will automatically be quoted, lists will be represented with [...], etc.

  With this change, a new GraphQLEnum wrapper class was added to allow users to still use Enum types in their GraphQL calls using templates.

  If this is still not enough, a literal format specifier can be used:
  ${var:literal}

• BREAKING: Add support for per-operation cost limit (#3)

  Field builders can now define the COST of the call as a class attribute.

  Operation builder must now define the MAX_COST of a single operation.
  This can be set to None to disable the limit.
