!! 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
!!

!!**** *ZRIDDR* - iterative algorithm to find root of a function
!!
!!
!! PURPOSE
!! -------
!! The purpose of this function is to find the root of a given function
!! the arguments are the brackets bounds (the interval where to find the root)
!! the accuracy needed and the input parameters of the given function.
!! Using Ridders' method, return the root of a function known to lie between
!! PX1 and PX2. The root, returned as PZRIDDR, will be refined to an approximate
!! accuracy PXACC.
