property CosmologyBase.get_mead_growth_fnc

Solve the linear growth ODE and returns an interpolating function for the solution. TODO: w dependence for initial conditions; f here is correct for w=0 only. TODO: Could use d_init = a(1+(w-1)/(w(6w-5))*(Om_w/Om_m)*a**-3w) at early times with w = w(a<<1).
