 * Introduction
 * ============================================================================
 *
 * This plugin requires YEP_EquipBattleSkills. Make sure this plugin is located
 * under YEP_EquipBattleSkills in the plugin list.
 *
 * This plugin adds Optional Extenstions to Yanfly Equip Battle Skills &
 * Yanfly Equip Battle Skills Tiers
 *
 * Minimum Tier X:
 * Where Tier X has a minimum number of skills that must be equipped.
 * If it's set to 0, then there is no minimum requirement however if it is more
 * 0, that will be the number of skills that must be equipped
 * This Requires YEP_X_EquipSkillTiers
 *
 *
 *
 * Script Calls:
 * replace "actor" with:
 * $gameActors.actor(z) where z is the actor id.
 * $gameParty.members()[y-1] where y is the postion the member is.
 *
 *
 *
 * actor.isSkillEquipped(y)
 * Checks if actor has skill y equipped returns true or false
 *
 * actor.isNotSkillEquipped(y)
 * Checks if actor  does not has skill y equipped returns true or false
 *
 *
 * $gameParty.alterMaxTier(x, y)
 * Increase or Decrease the maximum amount of skills that can be be equipped for each tier.
 * Where x is the tier id and y is the amount you want to add or subtract to
 * maximum amount
 * Note the maximum can't go over the maximum number of skills that can be equipped.
 * This Requires YEP_X_EquipSkillTiers
 * Examples:
 * $gameParty.alterMaxTier(1, 2) increases the maximum amount of tier 1 skills that can
 * be equipped by 2.
 * $gameParty.alterMaxTier(3, -2) decreases the maximum amount of tier 3 skills that can
 * be equipped by 2.
 *
 *
 *
 * $gameParty.setMaxTier(x, y)
 * Sets the maximum amount of Tier x slots.
 * For example if the hardcode limit is 10 for tier 1.
 * Use this to set it to 12 or 8.
 * This Requires YEP_X_EquipSkillTiers
 * Examples:
 * $gameParty.setMaxTier(3, 12) sets the maximum amount of skills that can be equipped for Tier 3 to 12.
 * $gameParty.setMaxTier(6, 8) sets the maximum amount of skills that can be equipped for Tier 6 to 8.
 *
 *
 * $gameParty.alterMinTier(x, y)
 * Increase or Decrease the minimum amount of skills that must be equipped for each tier.
 * Where x is the tier id and y is the amount you want to add or subtract to
 * minimum amount
 * Note the minimum can't go over the maximum number of skills that can be equipped.
 * This Requires YEP_X_EquipSkillTiers
 * Examples:
 * $gameParty.alterMinTier(1, 2) increases the minimum amount of tier 1 skills that must
 * be equipped by 2.
 * $gameParty.alterMinTier(3, -2) decreases the minimum amount of tier 3 skills that must
 * be equipped by 2.
 *
 * $gameParty.setMinTier(x, y)
 * Sets the minimum amount of Tier x slots.
 * For example if the hardcode minimum limit is 1 for tier 1.
 * Use this to set it to 0 or 2.
 * This Requires YEP_X_EquipSkillTiers
 * Examples:
 * $gameParty.setMinTier(3, 0) sets the minimum amount of skills that must be equipped for Tier 3 to 0.
 * $gameParty.setMinTier(6, 3) sets the minimum amount of skills that must be equipped for Tier 6 to 3.
 *
 *
 * $gameParty.alterMaxSlots(y)
 * Increase or Decrease the maximum amount of skill slots, of the hardcoded limit.
 * For example if the hardcode limit is 10. Use this to increase it to 12. Or decrease
 * it for 8. Note this is for the entire party not just a single actor.
 * Examples:
 * $gameParty.alterMaxSlots(2) increases the max amount of skills by 2.
 * $gameParty.alterMaxSlots(-2) decreases the max amount of skills by 2.
 *
 *
 * $gameParty.setMaxSlots(y)
 * Sets the maximum amount of skill slots, of the hardcoded limit.
 * For example if the hardcode limit is 10. Use this to set it to 12 or 8.
 * Examples:
 * $gameParty.setMaxSlots(12) sets the max amount of skills to 12.
 * $gameParty.setMaxSlots(8) sets the max amount of skills to 8
