Femwater Request: Mualem-van Genuchten model

I wondered if you could include the following change to GMS-FEMWATER.

In the van Genuchten Curve Generator, you have the classic van Genuchten parameters: theta_sat, theta_res, alpha, beta.

In more recent Mualem-van Genuchten models, an additional dimensionless parameter "L" is included, that only affects relative hydraulic conductivity, Kr. See attached paper.

Instead of

Kr = Se^0.5 *(1-(1-Se^1/gamma)^gamma)^2

where Se is the saturation, we would have

Kr = Se^L *(1-(1-Se^1/gamma)^gamma)^2
