In PAC: Partition-Assisted Clustering and Multiple Alignments of Networks

Makes constellation plot, in which the centroids are clusters are embedded in the t-SNE 2D plane and the cross-sample relationships are plotted as lines connecting related sample clusters (clades).

1 2	constellationPlot(pacman_results, perplexity, max_iter, seed, plotTitle = "Constellations of Clades", nudge_x = 0.3, nudge_y = 0.3)

`pacman_results`	PAC-MAN analysis result matrix that contains network annotation, clade IDs and mean (centroid) clade expression levels.
`perplexity`	perplexity setting for running t-SNE
`max_iter`	max_iter setting for running t-SNE
`seed`	set seed to make t-SNE and consetllation plot to be reproducible
`plotTitle`	max_iter setting for running t-SNE
`nudge_x`	nudge on x coordinate of centroid labels
`nudge_y`	nudge on y coordinate of centroid labels
