CodepointIterator

... is a std::iterator derived class implementing the std::bidirectional_iterator_tag which iterates through unicode codepoints in a UTF8-encoded string.

Current features:

• Bidirectional iteration through unicode codepoints
• The class itself does not rely on any external libraries
• Dereferencing an instance of the iterator yields the codepoint as char32_t
• Unit Tests based on GoogleTest

Requirements:

• GoogleTest for tests
