In pierrejacob/unbiasedpathsampling: Unbiased Path Sampling with couplings

Compute histograms based on coupled Markov chains.

1 2	histogram_c_chains(c_chains, component, k, K, breaks = NULL, nclass = 30)

`c_chains`	list containing pairs of chains generated by `coupled_chains`
`component`	index of the desired marginal distribution
`k`	tuning parameter representing 'burn-in'
`K`	tuning parameter representing 'total number of iteration per estimator'
`breaks`	vector of breaks (default to NULL)
`nclass`	desired number of classes; either specify this or `breaks` (default to 30)
