     * <p>Controls a NPCs Pushable Trait. When a NPC is 'pushable', the NPC
     * will move out of the way when colliding with another LivingEntity.</p>
     *
     * <p>Pushable NPCs have 3 different settings available: Toggled, Returnable, and Delay</p>
     *
     * <p>When an NPCs Pushable Trait is toggled off, it will not function. Entities which
     * collide may occupy the same space. To toggle pushable on or off, use the Bukkit command:</br>
     * <code>/npc pushable -t</code>
     * </p>
     *
     * <p>Setting the NPC as 'returnable' will automatically navigate the NPC back to
     * its original location after a specified delay. If not returnable, NPCs will retain
     * their position after being moved.</br>
     * <code>/npc pushable -r</code>
     * </p>
     *
     * <p>To change the delay of a returnable NPC, use the following Bukkit Command,
     * specifying the number of seconds in which the delay should be.</br>
     * <code>/npc pushable --delay #</code></p>
     *
     * <p>It is possible to use multiple arguments at once. For example:
     * <code>/npc pushable -t -r --delay 10</code></p>
     *
     * <p>Note: If allowed to move in undesirable areas, the NPC may be un-returnable
     * if the navigator cancels navigation due to being stuck. Care should be taken
     * to ensure a safe area around the NPC.</p>

     *
     * <p>Constants may be used in several ways: Setting, Removing, and Viewing</p>

     * <p>To set a constant, all that is required is a name and value. Use the Bukkit command in the

     * <code>/npc constant --set constant_name --value 'multi word value'</code></p>
     *
     * <p>Removing a constant from an NPC only requires a name. Note: It is not possible to remove a
     * constant set by the NPCs Assignment Script, except by modifying the script itself.
     * <code>/npc constant --remove constant_name</code></p>
     *
     * <p>Viewing constants is easy, just use <code>/npc constant #</code>, specifying a page number.
     * Constants which have been overridden in the Assignment Constants list are formatted with a
     * 'strike-through' to indicate this case.
     *
     * <p>To reference a constant value, use the Denizen Replaceable TAG format <code>&#60;CONS:name></code>.
