!! PURPOSE
!! -------
!! The purpose of this routine is to compute the activation of CCN
!! according to Cohard and Pinty, QJRMS, 2000
!!
!!
!!** METHOD
!! ------
!! The activation of CCN is checked for quasi-saturated air parcels
!! to update the cloud droplet number concentration.
!!
!! Computation steps :
!! 1- Check where computations are necessary
!! 2- and 3- Compute the maximum of supersaturation using the iterative
!! Ridder algorithm
!! 4- Compute the nucleation source
!! 5- Deallocate local variables
!!
!! Contains :
!! 6- Functions : Ridder algorithm
