Ichthyostega 974c670d41 fix **** in doxygen comments
to make them stand out more prominently, some entity comments
where started with a line of starts. Unfortunately, doxygen
(and javadoc) only recogise comments which are started exactly
with /**

This caused quite some comments to be ignored by doxygen.
Credits to Hendrik Boom for spotting this problem!

A workaround is to end the line of stars with *//**
