 *
 * Keeps track of your reputation with various factions & friends.
 *
 * Note: for convenience of management, you'll need to create a Variable for
 * each faction that you're keeping track of. These must be named like so:
 * KruRep:Your Group Name
 *
 * To increase or decrease your character's reputation, just increase the value
 * of the variable.
 *
 * You can give discounts at shops by running this script before 'Shop Processing':
 * KruFactionDiscountPrice('Faction Name', 'Known', '-10%'); // To use a percentage
 * KruFactionDiscountPrice('Faction Name', 'Known', -20); // For a flat amount
 *
 * You can also increase your character's sell price from the default (505) at
 * these shops with:
 * KruFactionSellBonus('Famous', '20%'); // To use a percentage
 * KruFactionSellBonus('Famous', 30); // For a flat amount
 *
 * @param Menu Name
 * @desc The name of the menu item to look at your faction status.
 * @default Factions
 *
 * @param Reputation Levels
 * @desc Names for different reputation levels.
 * @default Despised:-100, Hated:-50, Unknown:0, Familiar:50, Known:100
 *
 * @param Show Unknown Factions
 * @desc Show factions that haven't been discovered yet on the menu?
 * @type boolean
 * @on Yes
 * @off No
 * @default true
 *
 * @param Icons
 * @desc Name of the icon file to use, in img/system, without the file extension.
 * @type file
 * @dir img/system
 *
 * @param Icon Size
 * @parent Icons
 * @type number
 * @desc Size of the icons to use.
 * @default 32
 *
 * @param Custom Icons
 * @parent Icons
 * @desc By default, the icons will be determined by their order in the variables. This option allows you to override the default.
 * @type struct<CustomIcon>[]
 *
 * Terms & Conditions
 * This plugin is free for non-commercial and commercial use.
 */

/*~struct~CustomIcon:
 * @param Faction
 * @type variable
 *
 * @param Icon
 * @desc The index of the icon in the icon file. 0 is the first icon, etc.
