Lay some ideas on us. =)

I don't think the user base is big enough to really overhaul stuff. We
should take either the current format or the most recent working format
as the "old" format, and maybe provide an import for that.

Overhauling the save format will be crucial to making progress on the
new parts library...

One critical issue with the parts library is to maintain the
cleanliness, ease of use of the current parts library, It should still
be possible to say "Gimme a PNP transistor" with great ease. and still
be able to go in and select a specific PNP transistor...

One obvious solution for the equation editor is to simply use the
standard: http://www.w3.org/Math/

Granted, ktechlab will need standardized variables to access Cbranches
and Cnodes, and other variables in the matrix and simulator.

The old code for the probe data used an ugly/custom vector class... I
converted it to the standard vector class... main problem with the
current code is that if you leave it running all day, the buffers will
grow without bounds... (that should be a FIXME actually..) workaround:
just hit reset every few minutes...
