#    1. <unison actors: ids>                                                   |
#       - Sets the list of id of actors needed for the skill/item as ids.      |
#         For example:                                                         |
#         <unison actors: 1> means actor with id 1 is required to use it       |
#         <unison actors: 4, 2> means actors with id 4 and 2 are needed        |
#       - All actors in list ids needs to be in the battle, inputable, able to |
#         use it and pay its cost. They'll all pay the cost after using it.    |
#         Only actors in list x can select it.                                 |
#    2. <unison def rule: rule                                                 |
#       - Sets the rule of setting user's def in the skill/item's damage       |
#         formula as rule, whose symbol is one of those in UNISON_RULES.       |
#       - The symbol of def must be included in UNISON_DEFS                    |
#       - This notetag needs to be written below <unison item: ids> to work.   |
#    3. <unison def actors: ids>                                               |
#       - Sets user's method def in the skill/item's damage formula to use its |
#         unison rule to combine those of actors with id includedin the list   |
#         ids. def needs to be able to take no arguments and return a Numeric  |
#         to work.                                                             |
#         For example:                                                         |
#         <unison atk actors: 1> means the user's atk in its damage formula    |
#         uses thatof actor with id 1                                          |
#         <unison mat actors: 4, 2> means the user's mat in its damage formula |
#         uses mat of actors with id 4 and 2 under the skill/item's unison rule|
#       - The symbol of def must be included in UNISON_DEFS                    |
#       - This notetag needs to be written below <unison item: ids> to work.   |
