	* it is not the responsibility of a codepoint iterator to cache the resolved codepoint for reuse if this is required by the user of this class can iterate it better in the context it is required e.g. implement a "CachedIterator" template

	* CodepointIterator is a simple C++ iterator class which iterates through unicode codepoints in a UTF8-encoded string * It is derived from std::iterator and implements the std::bidirectional_iterator_tag * Dereferencing an instance of the class provides the codepoint as char32_t * Tests require Google Test and use UTF8-samples from http://www.columbia.edu/~fdc/utf8/
