/**
 * URLJoin
 *
 * @param {...string} args - URL segments to join
 * @returns {string} - The joined and normalized URL
 * @description
 * Joins all given URL segments together, then normalizes the resulting URL.
 *
 * Use String.prototype.join('/') to combine URL segments, then a series of String.prototype.replace() calls with various regexps to normalize the resulting URL (remove double slashes, add proper slashes for protocol, remove slashes before parameters, combine parameters with '&' and normalize first parameter delimiter).
 * @example
 *
 * URLJoin('http://www.google.com', 'a', '/b/cd', '?foo=123', '?bar=foo');
 * // => 'http://www.google.com/a/b/cd?foo=123&bar=foo'
