/*! \file
    Defines basic split algorithms. 
    Split algorithms can be used to divide a string
    into several parts according to given criteria.
    
    Each part is copied and added as a new element to the
    output container.
    Thus the result container must be able to hold copies
    of the matches (in a compatible structure like std::string) or
    a reference to it (e.g. using the iterator range class).
    Examples of such a container are \c std::vector<std::string>
    or \c std::list<boost::iterator_range<std::string::iterator>>
