Pathways analysis for stable nuclides

[fthomas]

Hello all,
I'd like to request a feature for the next code version.

The code has plenty of options to influence the printing of pathways and uncertainty analysis for active nuclides (typically ordered by activity at a given timestep). However, the pathways that lead to stable nuclides are not available. I am interested in the routes to He-4 in a block of tungsten. I appreciate I could check the (n,alpha) reaction rate values in the printlib output and multiply them by the atomic density of each nuclide in the meantime. However, I would appreciate the ability to do full pathways analysis on this stable nuclide just like I can for the radioactive nuclides in future...

Cheers,
Fred
