In "le_grids_knobs", "le" refers to "lambda-energy" grid.

New default (not backwards compatible), is to use the Candy-Waltz energy
grid (advanced_egrid=T):

set negrid ~ 10-16 good (16 parallelizes well on Seaborg)

set ecut ~ 6 (equivalent to ecut ~ 2.5 in old method)

set conserve_momentum=.false.  

(because momentum conservation model is not really correct for e-i
collisions, and slows down code by a factor of 2-3).
