Added support for haploid markers (#14, @krshedd).

Added support for individuals of known origin (i.e. those identified with great accuracy using parentage-based tagging) in the mixtures (#12).

Allow user to specify the total weight on the symmetrical Dirichlet prior for the mixing proportions in infer_mixture().

Enforced the requirement that fish of sample_type == “mixture” must have NA for their repunit. When things aren’t NA, infer_mixture() would throw an error when method == “PB” because there were extra factor levels floating around. In the process I allow for the repunit column to be either character or logical as setting it to NA will always make it a logical if it is not part of a data frame with other non-missing character values in it.

Modified vignette so that we don’t have to put tidyverse in the Suggests

Added support for user specified parameters for the Dirichlet prior on mixing proportions

Added support for user-specified initial starting values for the pi parameter (the mixing proportions of collections) in the function infer_mixture().

Added a simple function, close_matching_samples(), to tabulate pairs of individuals with only a small number of mismatching genotypes. This is useful for identifying accidentally duplicated samples. (#23)

Made changes to be compatible with dplyr 0.8.0, which no longer discards empty factor levels. Mostly this involved filtering 0’s after group_by() and tally() or count() calls. It looks like things are all working (passing all tests and building vignettes all right.)
