In melmasri/HPprediction: Host-parasite prediction based on phylogeny

This function samples the affinity and phylogeny scaling parameters from the posterior and constructs the posterior probability matrix 'P'. Dimension names are assigned from matrix 'Z'.

1	sample_parameter(param, MODEL, Z, tree, size = 1000, weights = NULL)

`param`	posterior parameter estimates generated by `network_est`
`MODEL`	indicate model used: one of 'full', 'distance', 'affinity'
`Z`	bipartite interaction matrix
`tree`	'phylo' object representing rows of Z
`size`	the number of posterior samples to use for each parameter (default is 1000)
`weights`	indicator of weights to use (optional)
