Update dimensionless alpha's


INTERFACE:

   subroutine alpha_mnb(nlev,NN,SS)
DESCRIPTION:

This subroutine updates the dimensionless numbers $ \alpha_M$, $ \alpha_N$, and $ \alpha_b$ according to (47). Note that according to (66) and (69) the following identities are valid

$\displaystyle \alpha_M = \overline{S}^2 \; , \quad \alpha_N = \overline{N}^2 \; , \quad \alpha_b = \overline{T} \quad .$ (151)
