This subroutine computes the thermal conductivity for frozen soil, using the Johansen method.

Farouki, O.T., "Thermal Properties of Soils", Chapter 7: Methods for Calculating the Thermal Conductivity of Soils, 1986

Variable	Type	Units	Description
moist	double	fraction	Fractional moisture content of soil layer
Wu	double	fraction	Fractional unfrozen moisture content of soil layer
soil_density	double	kg/m^3	Partical density of soil
bulk_density	double	kg/m^3	Bulk density of soil
quartz	double	fraction	Quartz content of soil

Variable	Type	Units	Description
K	double	W/m/K	Soil thermal conductivity

Currently based on quartz content set as constant in source code
