Heat equation, take 2

I've further implemented code to manage different electron-beam events. Now you can give it beam parameters at different times; electron-beam energy and electron number is converted to heat inside the slab at specific geometrical coordinates with different electron density distributions.
In this example, the electrons penetrate the slab in a cylinder distribution form with uniform density from the slab surface (z=0) until z=zmax/2=16/2=8 units. 1E22 electrons are converted to heat each second (ns actually) in that cylindrical space between t=10 and t=100, whereafter you can see it even out by diffusion.
Blackbody radiation is there but the time is much shorter than the last example and here the initial temperature of the slab is close to the ambient temperature, so BB effects are not noticable.
Lastly, Temperature Strength is now an average over z-axis.
