SelfRegulation

---

Determines the species specific self-regulation of the seed bank. This means the number of seeds in the seed bank increases with the input into it but is limited. This self regulation is done

1. either by the dynamics of species specific seed antagonists and their grazing,
2. or alternatively a logistic model type regulation of the seed bank
   1. The antagonist dynamics is replaced by a simple carrying capacity
   2. This is assumed to work continuously during each year. That means the dynamics is a solved logistic equation.

      Todo

      : understand why in thiscell there is sb and seedbank ß

      Parameters

      nspc	: number of species
      doDispersal	: flag, explicit dispersal?
      thiscell	: state of this cell before selfregulation
