The route map is an associative array with path regexes as the keys. The
value is an indexed array with the callback function/method as the first
item, and a bitmask of HTTP methods as the second item (see the class
constants).
Each route can be mapped to more than one callback by using an array of
the indexed arrays. This allows mapping e.g. GET requests to one callback
and POST requests to another.
Note that the path regexes (array keys) must have @ escaped, as this is
used as the delimiter with preg_match()

| Результат | array | `'/path/regex' => array( $callback, $bitmask )` or `'/path/regex' => array( array( $callback, $bitmask ), ...)`. |
