* Add python typing module as build dependency
* Change output_declarations to be a NamedTuple
* Add mypy configuration files
mypy-files.txt includes a list of all files that should be typed checked
with mypy. Run mypy with `mypy @mypyfiles.txt`.
mypy.ini includes mypy options. Unfortunately this can't be merged with
mypy-files.txt.
Update .travis.yml so that one doesn't have to specify what files to
type check inside it.
* Add RuntimeError on missing `typing` module
Alerts users to the new build dependency.
