Objective function for overdispersed binomial mixture model

1 2	up_bb_obj(pival, p1geno, p2geno, rho, out_mu, out_rho, ocounts, osize, qarray, r1vec, r2vec, pk)

`pival`	A fudge factor. The probability of not begin a mistake. Estimated if `est_fudge = TRUE`. Set to 0.99. Only used if `est_fudge = TRUE`.
`p1geno`	The genotype of parent 1. From 0 to ploidy.
`p2geno`	The genotype of parent 2. From 0 to ploidy.
`rho`	The overdispersion parameter.
`out_mu`	The outlier mean.
`out_rho`	The outlier overdispersion parameter.
`ocounts`	A vector of non-negative integers. The observed number of A's.
`osize`	A vector of positive integers. The observed total counts.
`qarray`	An three-way array of proportions. The (i, j, k)th element is the probability of an offspring having k - 1 reference alleles given that parent 1 has i - 1 refrerence alleles and parent 2 has j - 1 reference alleles. Each dimension of the array is `ploidy + 1`.
`r1vec`	A vector of prior probabilities whose ith element is the prior probability that parent 1 has i -1 copies of allele A.
`r2vec`	A vector of prior probabilities whose ith element is the prior probability that parent 2 has i -1 copies of allele A.
`pk`	The parameter space. Should all be between 0 and 1.
