Ok, now the availability report is actually usable.

Ok, now the availability report is actually usable.

 1. You can see the availability of a person for all relevant days at
    the very first glance, since all times are added in one row.

 2. All time shifts for a person are cumulated in the same cell, which
    should improve readability a lot.

 3. The table is a bit wide, though...  Not too wide, but still too
    wide.

 4. If the table is too wide or too large the user is able to limit
    the output to certain days of intrest (i.e. only thu-sun or only
    tue-wed).  Limitation to sections (i.e. all people working at the
    business congress or helping with workshops) is not yet
    implemented due to a) not enough test data and b) requirement of
    external functions.

 5. Oh, btw. limiting the SQL query like "AND starttime in
    ('2002-06-04','2002-06-05')" had interesting but not expected
    results, hence, it's been implemented different.
