Feature: re-simulate dynamically in the background

[GoogleCodeExporter]

It would be useful if simulations could be automatically updated whenever a 
parameters is changed. So, for example, the effect of varying the length of 
wire on the 3D pattern (or impedance) could be immediately seen.

Perhaps also the cells in the elements panels could be changed from edit boxes 
to spin boxes to make varying values easier.

After playing with it for a full 30 minutes, my guess is that that the data 
sets are stored as graphics, not necessarily as full-precision scientific data. 
This means that you likely can't extract or manipulate your data beyond your 
initial simulation runs.

A change to the simulation card always almost always requires new data. 
Especially if you're simulating a narrow band antenna or EM structure (e.g. a 
TE10 rectangular waveguide).

Introducing this functionality could also introduce new issues. If I'm working 
on a complex antenna design (2,000+ wires), I would not want the simulation to 
restart every time I wanted to make small changes to the simulation card. I 
would want to make all of my changes, document them, THEN call the simulation 
to start.
