Extended the StringTokenizer and U32StringTokenizer
classes with functions that provide the caller with a list
of all delimiters surrounding the last processed token.
Adding @defgroup and @ingroup doxygen tags into all headers
in the common folder that contain doxygen blocks.
This improves the structure, readability, and findability
of information in the resulting output.
This commit targets purely structure and does not deal with
the content of the currently existing doxygen documentation.
