/**
 * Create a RichText value from an `Element` tree (DOM), an HTML string or a
 * plain text string, with optionally a `Range` object to set the selection. If
 * called without any input, an empty value will be created. If
 * `multilineTag` is provided, any content of direct children whose type matches
 * `multilineTag` will be separated by two newlines. The optional functions can
 * be used to filter out content.
 *
 * A value will have the following shape, which you are strongly encouraged not
 * to modify without the use of helper functions:
 *
 * ```js
 * {
 *   text: string,
 *   formats: Array,
 *   replacements: Array,
 *   ?start: number,
 *   ?end: number,
 * }
 * ```
 *
 * As you can see, text and formatting are separated. `text` holds the text,
 * including any replacement characters for objects and lines. `formats`,
 * `objects` and `lines` are all sparse arrays of the same length as `text`. It
 * holds information about the formatting at the relevant text indices. Finally
 * `start` and `end` state which text indices are selected. They are only
 * provided if a `Range` was given.
 *
 * @param {Object}  [$1]                      Optional named arguments.
 * @param {Element} [$1.element]              Element to create value from.
 * @param {string}  [$1.text]                 Text to create value from.
 * @param {string}  [$1.html]                 HTML to create value from.
 * @param {Range}   [$1.range]                Range to create value from.
 * @param {string}  [$1.multilineTag]         Multiline tag if the structure is

 * @param {Array}   [$1.multilineWrapperTags] Tags where lines can be found if
 *                                            nesting is possible.
