	Slicer (int Dim, const V &scale, int kmax=10)
void	run (L &lnprob, std::vector< V > &chain, V xo, R &ran, int step_type, bool verbose=false)
	run the MC chain
size_t	number_evaluations ()
	returns the number of evaluations of the posterior during the last run

Detailed Description

template<typename V, typename L, typename R>
class Slicer< V, L, R >

This is a slice sampler that can be used to do a markov chain without repeated entries in the chain.

types; V is usuatly a std::vector<float> or std::vector<double> L is the functor type used for the likelihood function, this functure should have a opertor()(V p) that will return the log of the likeliwood
