/**
 * Text range module for Rangy.
 * Text-based manipulation and searching of ranges and selections.
 *
 * Features
 *
 * - Ability to move range boundaries by character or word offsets
 * - Customizable word tokenizer
 * - Ignore text nodes inside <script> or <style> elements or those hidden by CSS display and visibility properties
 * - Do not ignore text nodes that are outside normal document flow
 * - Range findText method to search for text or regex within the page or within a range. Flags for whole words and case
 *   sensitivity
 * - Selection and range save/restore as text offsets within a node
 * - Methods to return visible text within a range or selection
 * - innerText method for elements
 *
