move fed computation from smokeview to fds

[gforney]

for various reasons, mainly because of memory requirements, an fed computation was put into smokeview rather than fds a long time ago. I think it makes more sense now for the computation to be done in fds. I'm trying to speed up smokeview and simplify some coding. taking out fed from smokeview would help a lot. if fed is performed in fds then the resulting slices could be passed to smokeview and smokeview could view them as before.

I'm going to punt on this. Adding FED to every grid cell in a 2D or 3D slice would be too memory intensive. I suggest you remove it from Smokeview and going forward people should do FDS point by point.

ok, I'll it out of smokeview
