This changeset fixes a huge pile of problems, as indicated in the
error log of the Doxygen run after merging all the recent Doxygen improvements
unfortunately, auto-linking does still not work at various places.
There is no clear indication what might be the problem.
Possibly the rather unstable Sqlite support in this Doxygen version
is the cause. Anyway, needs to be investigated further.
time handling is part of the library, while this
convenience shortcut relies on the Advice system,
which resides in the application lib.
To allow this kind of symbolic acces to a grid
entity defined "elesewhere", client code needs
to be linked against liblumieracore.so
especially this allows to use the Advice system
or the query resolvers from within library facilities
to refer to other implementation level services by name
