 * Returns the value of a matched element, or an array of values of all
 * matched elements. If a matched element is contenteditable, this helper
 * will return the html content of the element.
 *
 * @example
 *
 * // <input value="Lorem ipsum">
 *
 * import { create, value } from 'ember-cli-page-object';
 *
 * const page = create({
 *   value: value('input')
 * });
 *
 * assert.equal(page.value, 'Lorem ipsum');
 *
 * @example
 *
 * // <div contenteditable="true"><b>Lorem ipsum</b></div>
 *
 * import { create, value } from 'ember-cli-page-object';
 *
 * const page = create({
 *   value: value('[contenteditable]')
 * });
 *
 * assert.equal(page.value, '<b>Lorem ipsum</b>');
 *
 * @example
 *
 * // <input value="lorem">
 * // <input value="ipsum">
 *
 * import { create, value } from 'ember-cli-page-object';
 *
 * const page = create({
 *   value: value('input', { multiple: true })
 * });
 *
 * assert.deepEqual(page.value, ['lorem', 'ipsum']);
 *
 * @example
 *
 * // <div><input value="lorem"></div>
 * // <div class="scope"><input value="ipsum"></div>
 *
 * import { create, value } from 'ember-cli-page-object';
 *
 * const page = create({
 *   value: value('input', { scope: '.scope' })
 * });
 *
 * assert.equal(page.value, 'ipsum');

 * // <div><input value="lorem"></div>
