bool	adaptiveSampleSize
	A flag that indicates whether the CParticleFilterCapable object should perform adative sample size (default=false).
double	BETA
	The resampling of particles will be performed when ESS (in range [0,1]) < BETA (default is 0.5).
unsigned int	sampleSize
	The initial number of particles in the filter (it can change only if adaptiveSampleSize=true) (default=1).
unsigned int	pfAuxFilterOptimal_MaximumSearchSamples
	In the algorithm "CParticleFilter::pfAuxiliaryPFOptimal", the number of samples for searching the maximum likelihood value (see papers!) (default=100).
double	powFactor
	An optional step to "smooth" dramatic changes in the observation model to affect the variance of the particle weights, eg weight*=likelihood^powFactor (default=1 = no effects).
TParticleFilterAlgorithm	PF_algorithm
	The PF algorithm to use (default=pfStandardProposal) See TParticleFilterAlgorithm for the posibilities.
TParticleResamplingAlgorithm	resamplingMethod
	The resampling algorithm to use (default=prMultinomial).
