+ * operates by allowing the programmer to push users onto
+ * the list, each with a seperate quit reason, and then, once
+ * the list is complete, call a method to flush the list,
+ * quitting all the users upon it. A CullList may hold local
+ * or remote users, but it may only hold each user once. If
+ * you attempt to add the same user twice, then the second
