Combine mcmc samples

all functions in mcmc-tools.R are adapted from pmcmc-tools.R functions in github.com/mrc-ide/mcstate Combine multiple [mcmc()] samples into one object

mcmc_combine(..., samples = list(...))

Arguments

...	Arguments representing [mcmc()] sample, i.e., `gonovax_mcmc` objects. Alternatively, pass a list as the argument `samples`. Names are ignored.
samples	A list of `gonovax_mcmc` objects. This is often more convenient for programming against than `...`
