In dhimmel/hetior: Machine learning tools for hetnet edge prediction

Compute roc and prc curves as well as AUCs (area under the curves).

1	calc_vtms(y_true, y_pred, is_prob = FALSE)

`y_true`	true binary labels in binary label indicators
`y_pred`	target scores, can either be probability estimates of the positive class, confidence values, or binary decisions.
`is_prob`	whether predictions (y_pred) are probabilities. If so additional metrics are computed
