proposed patch

Have you made sure that the doxygen output is still ok ? 

If so, please, send an email to ns-dev asking for comments. If you don't get
any feedback, I will apply this patch in a week.

Actually no.  I am checking now and noticing that doxygen is not showing the
extra methods (e.g. GetSeconds ()) of TimeUnit<1>, and I don't really know how
to make it show those methods :(

patch v2, fix docs

I couldn't find a way to coerce doxygen to document the extra methods.  As a
workaround, I just described the added methods in the overview sections of the
type.
