    /// \brief This class represents a boundary point in the text. 
    ///
    /// It represents a pair - an iterator and a rule that defines this 
    /// point.
    ///
    /// This type of object is dereference by the iterators of boundary_point_index. Using a rule()
    /// member function you can get the reason why this specific boundary point was selected. 
    ///
    /// For example, When you use a sentence boundary analysis, the (rule() & \ref sentence_term) != 0 means
    /// that this boundary point was selected because a sentence terminator (like .?!) was spotted
    /// and the (rule() & \ref sentence_sep)!=0 means that a separator like line feed or carriage
    /// return was observed.
    ///
    /// \note
    ///
    /// -   The beginning of analyzed range is always considered a boundary point and its rule is always 0.
    /// -   when using a word boundary analysis the returned rule relates to a chunk of text preceding
    ///     this point.
