The former implementation of the daughterSizeDistributionModel based on
Laakkonen et al. (2006) had the issue of not conserving the total
particle number and volume properly, except when the coefficient C4 is
set to a value of 2. The issue is solved by following the work of
Laakkonen et al. (2007).
The default coefficients in both the breakupModel and the
daughterSizeDistributionModel were updated as well according to the
suggestions of the authors.
