Temperature and composition inputs to crack.sce

The kbo.dat file attached has 501 groups (evolution tracked over 501*10 million years = 5 billion years) of 200 lines (1-D slices inside the icy body Ceres of radius 200*2.375 = 475 km). The columns of kbo.dat represent respectively: distance from center in km, temperature in K, mass of silicate rock in g, mass of water ice in g, mass of  ammonia dihydrate (NH3.2H2O) in g, mass of liquid water in g, mass of liquid ammonia in g, Nusselt number, and fraction of ice that is amorphous.
