Fixed empty labels in Rd files of 'logitBvs', 'negbinBvs', 'pogitBvs', 'poissonBvs'.
New (invisible) function 'compute_mixture' since 'compute.mixture' from package BayesLogit (archived) is no longer supported.
DESCRIPTION file: Imports changed (BayesLogit removed)
New function 'negbinBvs' to deal with overdispersion of count data (and all affected functions).
Minor changes in 'poissonBvs' (uses now 'select_poissonOD' for observation-specific random intercept)
Minor changes in 'pogitBvs' (uses now 'select_poissonOD' for observation-specific random intercept)
Updated CITATION file to refer to newly published article in Statistical Modelling 16(1), 24 - 46, doi: 10.1177/1471082x15588398.
