docs: Creates a new handler that will only be called if it matches the given route info.
  @param method The method to match, or <code>null</code> to accept any method.
  @param uriTemplate A URL template. Supports plain URLs like <code>/abc</code> or paths
  with named parameters such as <code>/abc/{id}</code> or named parameters
  with regexes such as <code>/abc/{id : [0-9]+}</code> where the named
  parameter values can be accessed with the <code>pathParams</code>
  parameter in the route handler.
  @param muHandler The handler to invoke if the method and URI matches.
  @return Returns a {@link MuHandler} that is only called if the request URI and method matches.
