v1.1.3

• Added new InternalError class to represent non-doctor internal errors.
• Updated sphinx pin version to be minimum 1.5.4 and added new env kwarg to make_field and make_xref.
• Fixed bug where extra parameters passed on json requests would cause a TypeError if the logic function used a decorator.
• Made sure to make decorators a set when applying them to a logic function when creating routes. This is to prevent a decorator from wrapping a function twice if it's defined at the logic level and handler level when creating routes.
