Initial commit...

But after spending some half a way on the little project...
Now I am finally happy enogh to add some documentation to it and take care of
bits and pieces.
Mistake in .gitignore (doxygen.conf)
Add doxygen.conf to version control
Preliminary good condition.

Added dummy namespace and classes in case NDEBUG macros is used before
including this header. In this case all clases and objects (except IOManip)
are replaced with ones that don't work.
Add readme file.
create repository on GitHub.

Merge with local code and push.
