/**
 * 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.
