/** Activate particle settling and load parameters */
/*
* settleParams :
* [0] : settlingType :
* 0: no settling
* 1: flat settling all particles can settle at any time with probabylity given py [4] settleRateMax
* 2: all particle can settle with a probability that increases linearly between 0 in [1] tPreComp and [4] settleRateMax in [3] tSettleMax then decreases linearly to 0 in [2] tPostComp
* 3: all particles settles when they are competents, competency is aquired and lost with flat rate [5] compAquisitionRate and [6] compLossRate
* [7] : settleOverWhichReefType :
* 0: all reefs
* 1: only shallow reefs
* 2: only deep reefs
* reefs :
* a dof container with the id of the reef by element (0 = no reef)
* nbOfShallowReefs :
* reefs with id <= nbOfShallowReefs are shallow reefs, the others are deep reefs
