check_ott_input | Check input for usage in other 'datelife' functions
choose_cluster | Choose an ultrametric phylo object from 'cluster_patristicmatrix()' obtained with a particular clustering method, or the next best tree. If there are no ultrametric trees, it does not force them to be ultrametric.
classification_paths_from_taxonomy | Gets classification paths for a vector of taxa
