Derives the Gaussian parameters, μ and σ,
from specifications in the 'Mil-Std-414' style, i.e., with given AQL's,
for the lower and upper specs.
The application is illustrated with a Gaussian weight,
given w, its target value (kg), and
τ, (symmetrical) tolerance (%), related to the target.
The specifications thus become (L, U) =
w (1 ∓ τ).
