Split up soil into materials and soil nodes.
soil_to_param(soil, imodel = "MvG")Data.frame with soil layer boundaries ('upper', 'lower') and hydraulic parameters. When imodel = 'MvG', columns of soil have to be named 'ths', 'thr', 'alpha', 'npar', 'ksat', 'tort', 'gravel'. When imodel = 'CH', columns have to be named thsat , 'thetaf','psif', 'bexp','kf', 'wetinf', 'gravel'.
Name of the hydraulic model ('MvG' or 'CH')
a list with data.frames 'soil_nodes' and 'soil_materials'
