dirch_from_allocations

Takes a vector of collection indices to which individuals (vector elements) were assigned,
and returns a Dirichlet random variable generated by adding the prior to the sum
of each collection's occurrences, and simulating an alpha from a gamma distribution
with this shape parameter.

internal

Implements Bayesian inference for the conditional genetic
stock identification model. It allows inference of mixed fisheries and also
simulation of mixtures to predict accuracy. A full description of the underlying
methods is available in a recently published article in the
Canadian Journal of Fisheries and Aquatic Sciences: <doi:10.1139/cjfas-2018-0016>.
