// note 1: Besides function name, is essentially the same as parseUri as

// note 1: an extra slash after the scheme/protocol (to allow file:/// as in PHP)
// example 1: parse_url('http://user:pass@host/path?a=v#a')
// returns 1: {scheme: 'http', host: 'host', user: 'user', pass: 'pass', path: '/path', query: 'a=v', fragment: 'a'}
// example 2: parse_url('http://en.wikipedia.org/wiki/%22@%22_%28album%29')
// returns 2: {scheme: 'http', host: 'en.wikipedia.org', path: '/wiki/%22@%22_%28album%29'}
// example 3: parse_url('https://host.domain.tld/a@b.c/folder')
