* @help
* This plugin allows for randomising enemy hues.
* If 'use default hue' is checked, a default hue adjustment will be applied at 
* random to all enemies, based on the values defined in the plugin parameters.
* This is additive to whatever you have set in-editor.
*
* Additionally, the following notetags may be used in enemy noteboxes:
*
* <minhue:x>
* <maxhue:x>
* This sets the minimum/maximum hue adjustment of the enemy to be x.
* If only one is used, the other is assumed to be the default value specified in
* the plugin parameters.
* Maxhue must be higher than minhue. Negative numbers may be used.
* These values replace the defaults specified in the plugin parameters and are
* additive to the value defined in-editor.
*
* <randomhue>
* This sets the hue adjustment to be completely random.
* (i.e. all the possible hue variations from 0 - 359)
*
* <nohue>
* This sets the enemy to not have a hue adjustment, ignoring the defaults
* specified in the plugin parameters. (In-editor hue adjustments still apply)
*
* <defaulthue>
* If 'use default hue' is set to false, this notetag will override it for that
* enemy and use the default hue range specified in the plugin parameters.
* 
* <keephue>
* This makes the enemy keep the hue adjustment of the previous form after
* transforming, overriding the plugin setting. Use it on the transformed enemy.
*
* <rerollhue>
* This makes the enemy reroll the hue adjustment after transforming, overriding
* the plugin setting. Use it on the transformed enemy.
* This does not copy the notetags from the previous enemy; you will need to add
* them to the transformed enemy as well if you want to re-use the same settings.
*
* TERMS OF USE
* - Free for commercial and non-commercial use, as long as I get a free copy
*   of the game.
* - Edits allowed for personal use.
* - Do not repost or claim as your own, even if edited.
* 
* VERSION HISTORY
* v1.0 - 2023/7/1 - Initial release.
