v3.0.0 - December 22, 2018

Version 3 is a complete re-write of scrollnav to move the project away from
jQuery, update to the latest es6 features, and remove all production
dependencies. This update also removes a number of user options to simplify
the API and reduces the amount of DOM manipulation to reduce likelihood of
browser bugs. Includes a full set of test suites for all modules (unless
noted). Please read through the readme for further
details.
