# ║ Brief Description:                                                 ║
# ║   Adds returning of items if they are specified in the note tag    ║
# ║   Essentially making it so that you do not lose the tagged item    ║
# ╚════════════════════════════════════════════════════════════════════╝

# ║ Instructions:                                                      ║
# ║   I designed this for my own game Path of Life                     ║
# ║   The concept is that you can have items that are 'super' items    ║
# ║   which will not be lost and replace other items in the recipe     ║
# ║                                                                    ║
# ║   The tagged item must be in your inventory                        ║
# ║   Can only substitute items for items, weapons for weapons etc     ║
# ║                                                                    ║
# ║   Place the note tag                                               ║
# ║         <swap craft: X>                                            ║
# ║   on the item, weapon, armor you wish to be recovered              ║
# ║   in the item that would normally get consumed                     ║
# ║   So on item 15 you say <swap craft: 20>                           ║
# ║   The recipe needs item 15, but it gets substituted for item 20    ║
# ║   When you craft the item, item 20 is not lost, neither is item 15 ║
# ║                                                                    ║
