/**
* Serializer module for Rangy.
* Serializes Ranges and Selections. An example use would be to store a user's selection on a particular page in a
* cookie or local storage and restore it on the user's next visit to the same page.
*
* Part of Rangy, a cross-browser JavaScript range and selection library
* https://github.com/timdown/rangy
*
* Depends on Rangy core.
