at HunterGathererMDPState::~HunterGathererMDPState()
look out: if 'this' is an _initial of a HGMDPModel && step==361 && _agentRef killed at 360, then the next line produces segm fault :
commented line code : //logName << "logMDPStates_"	<< _agentRef->getWorld()->getId() << "_" << _agentRef->getId();

following the same idea : destroy _initial from MDPModel once you have finished the select_actions. Do not
leave any "trace" of data pending till the next uct execution. An agent death due to demography could make
you to  produce corrupt accesses.
