!!****  *MODD_PARAM_C2R2* - declaration of the control parameters
!!                               for use in the warm scheme.
!!
!!    PURPOSE
!!    -------
!       The purpose of this declarative module is to declare the microphysical
!     constants. This includes the descriptive parameters for the raindrop 
!     and the parameters relevant of the dimensional distributions.
!
!       The four constants used to set the actiavtion spectrum are also
!     defined
!
!          N_activated = (C*S**k)*F_hypgeo(mu,k/2,k/2+1;-beta*S**2) 
!         DN_activated/DS = k*(C*S**(k-1))*(1+beta*S**2)**-mu
