Allow multiple labels at once #2
Description
Current annotation mode is to specify "variables" and only choose a single label per variable. This is suitable when analyzing the presence or absence of a small number of species. Yet it will not work as well for annotating large groups of species. Provide an option to allow for multi-labeling that will treat a comma-separated list of strings (i.e. species) as variables instead of as labels, and allow multiple selection of variables, resulting in 1/0 labels for each variable. This will be enabled by #1.
