/**
 * Class to coordinate unique selection based on name.
 * Intended to be consumed as an Angular service.
 * This service is needed because native radio change events are only fired on the item currently
 * being selected, and we still need to uncheck the previous selection.
 *
 * This service does not *store* any IDs and names because they may change at any time, so it is
 * less error-prone if they are simply passed through when the events occur.
