/**
 * Tribe Dependency. Allows us to conditionally hide/show and disable elements
 * based on a data relationship.
 *
 * Glossary (in case you get lost like I did!)
 * dependent  = the element that is the "target" of the relationship the one that
 *                  is affected, thus dependent.
 * dependency = the element the relationship is based on the one we check in our conditions
 * active     = the class we use to denote an "active" (not hidden & enabled) element
 * selector   = the css selector for the dependency, must be an ID, includes the hash "#"
 * linked     = data attribute for linked dependents mainly for radio buttons to
 *                  ensure they all get triggered together
