Gerd,

We do need to eventually provide a grade extrapolator but I don't think the
spreadsheet is the right place/format for it.  I doubt anyone has really used
it as such...  Something similar in appearance to the 'quickgrades' page would
probably be worthwhile - currently they would have to specify each potential
homework grade instead of 'I will get all of the next homework set right'.

At the least I'm uncomfortable with giving the students the ability to tie
up the httpd with a 'while(1)' anytime they get pissed off at us...
