 * ============================================================================
 * Introduction
 * ============================================================================
 *
 * Skills in RPG's consist of three main components: Costs, Damage, and
 * Effects. Although not all components are required for a skill, they
 * certainly make up a good chunk of it. Damage will be handled by another
 * plugin, but this plugin will provide a core handling for skill costs and
 * skill effects.
 *
 * This plugin also includes the ability for battlers to swap their HP, MP,
 * and/or TP gauges for something different if it would fit the character
 * better (for example, some classes don't use MP and/or TP).
 *
 * ============================================================================
 * Notetags
 * ============================================================================
 *
 * These notetags can adjust either skill costs or special skill effects.
 *
 * Skill Notetags:
 *   <HP Cost: x>
 *   Changes the skill to have x as its HP cost. RPG Maker MV's editor lacks
 *   HP cost functions so this would allow skills to use HP as their cost.
 *
 *   <HP Cost: x%>
 *   Changes the skill to cost a percentage of the character's MaxHP value.
 *
 *   <MP Cost: x>
 *   Changes the skill to have x as its MP cost.
 *   This helps bypass the database's hard limit of 9999.
 *
 *   <MP Cost: x%>
 *   Changes the skill to cost a percentage of the character's MaxMP value.
 *
 *   <TP Cost: x>
 *   Changes the skill to have x as its TP cost.
 *   This helps bypass the database's hard limit of 99.
 *
 *   <TP Cost: x%>
 *   Changes the skill to cost a percentage of the character's MaxTP value.
 *   Although the default MaxTP is 100, this tag will be useful for any
 *   plugins that will alter a character's MaxTP values.
 *
 *   <Hide in Battle>
 *   This will hide and disable the skill during battle.
 *
 *   <Hide in Field>
 *   This will hide and disable the skill outside of battle.
 *
 *   <Hide if Learned Skill: x>
 *   <Hide if Learned Skill: x, x, x>
 *   <Hide if Learned Skill: x to y>
 *   Will hide and disable this skill if skill x has been learned. If multiple
 *   skills are listed, the skill will be hidden and disabled if any one of the
 *   listed skills have been learned. This will ONLY apply to skills that have
 *   been learned and not skills added through traits.
 *
 * ============================================================================
 * Gauge Swapping
 * ============================================================================
 *
 * This plugin also lets you swap around the HP, MP, and TP Gauges to any order
 * you want assuming that all the plugins you use will keep the same order of
 * HP, MP, and TP and does not override the default gauge drawing process. If
 * you use any plugin extensions, they can be swaped in as well.
 *
 * Note: If you do not have 'Display TP in Battle' checked under the System tab
 * in the database, nothing will be shown for the third slot.
 *
 * Class Notetag:
 *   <Swap Gauge x: y>
 *   This will change gauge x (1, 2, or 3) to y. Replace y with 'HP', 'MP', or
 *   'TP' to have it display that gauge type in that gauge slot. If you wish
 *   for that slot to display nothing, insert 'Nothing' or 'Null' in place of
 *   y in the notetag.
 *
 * Weapon, Armor, and State Notetags:
 *   <Swap Gauge x: y>
 *   Actors with equipment or states  that contain these notetags or enemies
 *   with states that contain these notetags will display those swapped gauges
 *   in place of the default settings or settings defined by the Class or
 *   Enemy notetags.
 *
 *   Priority will go in the following order:
 *     Weapons, Armors, States, Class, Enemy
 *
 * ============================================================================
 * Lunatic Mode - Skill Costs
 * ============================================================================
 *
 * For users who want more control over skill costs and skill effects, there
 * exists notetags that allow you to apply code to the costs and/or effects of
 * a skill. For effects, this will also extend towards item control, as well.
 *
 *   <Custom HP Cost>       Example: <Custom HP Cost>
 *    code                            cost += $gameVariables.value(1);
 *    code                           </Custom HP Cost>
 *   </Custom HP Cost>
 *   This allows the skill to have a custom HP cost based off of code. For the
 *   piece of code, 'cost' is a variable already predefined with the HP Cost
 *   and the HP percentage cost.
 *
 *   <Custom MP Cost>       Example: <Custom MP Cost>
 *    code                            cost += $gameVariables.value(1);
 *    code                           </Custom MP Cost>
 *   </Custom MP Cost>
 *   This allows the skill to have a custom MP cost based off of code. For the
 *   piece of code, 'cost' is a variable already predefined with the MP Cost
 *   and the MP percentage cost.
 *
 *   <Custom TP Cost>       Example: <Custom TP Cost>
 *    code                            cost += $gameVariables.value(1);
 *    code                           </Custom TP Cost>
 *   </Custom TP Cost>
 *   This allows the skill to have a custom TP cost based off of code. For the
 *   piece of code, 'cost' is a variable already predefined with the TP Cost
 *   and the TP percentage cost.
 *
 * ============================================================================
 * Lunatic Mode - Custom Show Requirements
 * ============================================================================
 *
 * For those who would like to show certain skills and disable them under any
 * custom conditions using their JavaScript knowledge, use the following:
 *
 * Skill Notetag:
 *   <Custom Show Eval>
 *   if (user.level > 50) {
 *     visible = true;
 *   } else {
 *     visible = false;
 *   }
 *   </Custom Show Eval>
 *   If the visible is set to true, the skill is shown (not hidden) and enabled
 *   if all other conditions are met. If visible is set to false, the skill is
 *   disabled and hidden from the list.
 *
 * ============================================================================
 * Lunatic Mode - Custom Requirements and Execution
 * ============================================================================
 *
 * For those with a bit of JavaScript experience, you can use the following
 * notetags to restrict a skill and what kind of code to process when executing
 * the said skill.
 *
 * Skill Notetags:
 *
 *   <Custom Requirement>
 *    if ($gameParty.gold() > 1000) {
 *      value = true;
 *    } else {
 *      value = false;
 *    }
 *   </Custom Requirement>
 *   If value is set to true, the skill will be useable provided that all other
 *   requirements have been met. If the value is set to false, the skill won't
 *   be useable.
 *
 *   <Custom Execution>
 *    $gameParty.loseGold(1000);
 *   </Custom Execution>
 *   This runs the code between the notetags upon using the skill.
 *
 * ============================================================================
 * Lunatic Mode - Custom Cost Display
 * ============================================================================
 *
 * For those with a bit of JavaScript experience, you can add new ways to
 * display the skill cost.
 *
 * Skill Notetags:
 *
 *   <Cost Display Eval>
 *    var variableId = 1;
 *    var value = 1000;
 *    $gameVariables.setValue(variableId, value);
 *   </Cost Display Eval>
 *   This notetag runs an eval before displaying the skill's cost. This is so
 *   you can set up variables and whatnot for your skill cost display text.
 *
 *   <Custom Cost Display>
 *    \c[4]\v[1]\c[0] Gold
 *   </Custom Cost Display>
 *   This is the custom text displayed before the rest of the skill costs. You
 *   can use text codes with this notetag.
 *
 * ============================================================================
 * Lunatic Mode - The Skill Phases
 * ============================================================================
 *
 * For this skill, multiple effects are applied and at different phases. The
 * various phases are as follows:
 *
 *    Before Effect Phase (influenced by this plugin)
 *    if skill successfully lands:
 *    - Pre-Damage Effect Phase (influenced by this plugin)
 *    - Damage Phase
 *    - Post-Damage Effect Phase (influenced by this plugin)
 *    - Item Trait Effects Phase
 *    After Effect Phase (influenced by this plugin)
 *
 * There's four phases which can be influenced by this plugin. Two of which do
 * not matter if the effect successfully lands or not, two of which do matter
 * if the skill does land.
 *
 * Skill and Item Notetags:
 *   <Before Eval>
 *    code
 *    code
 *   </Before Eval>
 *
 *   <Pre-Damage Eval>
 *    code
 *    code
 *   </Pre-Damage Eval>
 *
 *   <Post-Damage Eval>
 *    code
 *    code
 *   </Post-Damage Eval>
 *
 *   <After Eval>
 *    code
 *    code
 *   </After Eval>
 *   If you wish to use custom effects for your skill, you can insert the
 *   respective notetags into the skill (or item) noteboxes and it will run the
 *   code that appears in between the tags. However, using any form of comments
 *   in this tag will block out code that follows.
 *
 *   Those using the <Pre-Damage Eval> and <Post-Damage Eval> are able to make
 *   use of the damage to be dealt and the damage that has been dealt through
 *   the 'value' variable. The <Pre-Damage Eval> notetag is capable of altering
 *   the 'value' variable and return it to have damage affected by its code.
 *
