Gets the purity of a label vector wrt a ground truth (in the context of a clustering algorithm).

getPurity(truthLabels, inferLabels)

`truthLabels`	ground truth labels, to which inferred labels are compared to compute the purity value
`inferLabels`	vector of inferred labels, which should have the same length as truthLabels

purity value in [0,1]
