/// Some common principles
/// Most methods can be used in two way:
/// * to get value they are invoked without their last argument. Returned value is either a value or pair of nil and error message.
/// * to set value they are invoked with last arg (value) specified. Returned value in most cases is an object, on which operation is performed (to allow chain-initialization).
/// Every object have pointer method to return pointer (lightuserdata) to underlying C loudmouth structure.
/// Every module have a bless method to convert given pointer (lightuserdata) to corresponding lua object.
/// Every unique C loudmouth object have only one corresponding lua object. Thus, result of "lm.message.bless ( message1:pointer () )" will be exactly message1 object (not its copy).
/// Where message handler object is expected, message handler function can be specified. However, you can unregister handler only if you have message handler object.
