multiphaseEulerFoam::populationBalanceModel: improved dilatation treatment

Browse Source 
The population balance model considers dilatation originating from density
change and mass transfer via source terms describing nucleation as well as
"drift" of the size distribution to smaller or larger sizes. Numerically, the
treatment does not necessarily equal the total dilatation, hence a correction is
introduced to ensure boundedness of the size group fractions.
