    754 Switch on/off splitting algorithm for cloud droplets ( if [../inipar#cloud_droplets cloud_droplets]=.T.). If [#splitting splitting] is set .TRUE. every time step the splitting algorithm is executed. The algorithm split particles which fulfill certain criterion's into several super droplets with a reduced number of represented particles of every super droplet. The splitting algorithm can be steered by several parameters (a critical radius, a critical weighting factor,..). This mechanism allows an improved representation of the right tail of the drop size distribution with a feasible amount of computational costs. The limits of particle creation should be chosen carefully! The idea of this algorithm is based on Unterstrasser and Soelch, 2014.
