Given a full fused network (one containing both pre-labeled training subjects and unlabeled test-subjects) and the clusters of the pre-labeled subjects, return a label propagated list of clusters for all subjects. This function is derived from SNFtool::groupPredict. Modifications are made to take a full fused network as input, rather than taking input dataframes and running SNF internally. This ensures that alternative approaches to data normalization and distance matrix calculations can be chosen by the user.
