##### Rejection Rate for Metropolis--Hastings chains

rejectionRate calculates the fraction of time that a Metropolis--Hastings type chain rejected a proposed move. The rejection rate is calculates separately for each variable in the mcmc.obj argument, irregardless of whether the variables were drawn separately or in a block. In the latter case, the values returned should be the same.
