private pure function shear_estimate_2d(nvrstk, mean, deviation, grad) result(maxshear)
Estimate the magnitude of shear terms.
We use an estimate for mu(dv/dx) from the deviations and derivative
estimates of the conservative variables:
dm/dx = dv/dx * rho + drho/dx * v
dv/dx = (dm/dx - drho/dx * v)/rho
dv/dx < (max(dm/dx) - max(drho/dx) * max(v))/min(rho)
dv/dx < (max(dm/dx) * min(rho) - max(drho/dx) * max(m) ) / min(rho) *2

Solid arrows point from a procedure to one which it calls. Dashed
arrows point from an interface to procedures which implement that interface.
This could include the module procedures in a generic interface or the
implementation in a submodule of an interface in a parent module.
