ZObs for parameter reading

["Tuomas J. Lukka" <lukka@xxxxxx>]

Everyone coding should check flob/VanishingRaster.zob and zob2java.pl
currently in CVS. They are not yet quite complete but give an idea
of the direction the code is headed: parameter reading from the
structure will be slightly formalized and writing rasters will be
easier than ever.

Vesa, Tuukka: this is what is needed for the email stuff, you two
should discuss this subject to some length.

AJ: the vanishingraster code will get easier: no need for a separate 
"State" object since we have the Flob object. This may also affect
your treeraster.

I will try to finish the changes tomorrow on the train.
