docs: This method retrieves the structure id which is mapped to a given URL name.<p>
  
  If there is no structure id mapped to the given name, null will be returned.<p>
  
  However if the parameter is a string which represents a valid uuid, it will be directly returned as a {@link CmsUUID} instance.<p>
  
  @param name the url name
  @return the id which is mapped to the URL name
  
  @throws CmsException if something goes wrong
