/**
 * Conditionally joining classNames together.
 *
 * The cx function takes any number of arguments which can be a string, object
 * even nested arrays of strings and objects.
 *
 * The argument 'foo' is short for { foo: true }.
 *
 * If the value associated with a given key is falsy, that key won't be included in the output.
 *
 * @func
 * @category String
 *
 * @example
 *
 *        R_.cx('Table', ['MagicTable'], {'Table--active': true })	// 'Table MagicTable Table--active'
 *        R_.cx('Table', ['MagicTable'], {'Table--active': false })	// 'Table MagicTable'
 *        R_.cx(['Table', ['MagicTable']])				// 'Table MagicTable'
 *
 * @sig String | [String] | Object -> String
