-/**
- * This is an extended version of the NMS.PlayerInventory.
- * It is extended in such a way that it has a no-arg constructor.
- * It is mainly used for deserialization of PlayerInventor.
- * 
- * There is a link/field to the holder/player.
- * We override internal methods where necessary.
- * 
- * How to update:
- * https://github.com/Bukkit/CraftBukkit/commits/master/src/main/java/net/minecraft/server/PlayerInventory.java
- * Make sure there is a no-arg constructor.
- * Search for references to "public EntityHuman player".
- * 
- * As of 1.5.1 these are the references:
- * 
- * a(EntityHuman) (2 matches)
- * g(int)
- * getOwner()
- * k() (2 matches)
- * m() (2 matches)
- * pickup(ItemStack) (2 matches)
- * PlayerInventory(EntityHuman)
- * 
- * As of 1.6.1 and 1.6.2 and 1.6.4 and 1.7.2 and 1.7.5 and 1.7.8 and 1.7.10 these are the references:
- * 
- * a(EntityHuman) (2 matches)
- * a(float)
- * getOwner()
- * k() (2 matches)
- * m() (2 matches)
- * pickup(ItemStack) (2 matches)
- * PlayerInventory(EntityHuman)
