/**
 * Class CRM_Member_Tokens
 *
 * Generate "activity.*" tokens.
 *
 * This TokenSubscriber was originally produced by refactoring the code from the
 * scheduled-reminder system with the goal of making that system
 * more flexible. The current implementation is still coupled to
 * scheduled-reminders. It would be good to figure out a more generic
 * implementation which is not tied to scheduled reminders, although
 * that is outside the current scope.
 *
 * This has been enhanced to work with PDF/letter merge
