/**
 * Factory to encode HTML entities.
 * Creates a no-operation function when `type` is
 * `'false'`, a function which encodes using named
 * references when `type` is `'true'`, and a function
 * which encodes using numbered references when `type` is
 * `'numbers'`.
 *
 * @example
 *   encodeFactory('false')('AT&T') // 'AT&T'
 *   encodeFactory('true')('AT&T') // 'AT&T'
 *   encodeFactory('numbers')('AT&T') // 'ATT&T'
 *
 * @param {string} type - Either `'true'`, `'false'`, or
 *   `'numbers'`.
 * @return {function(string): string} - Function which
 *   takes a value and returns its encoded version.
