/**
The label component.
This component is used to manage labels applied by the hand labeler.
Atoms can only have one instance of this component, and therefore only one label at a time.
This is to avoid having names like "Backpack (label1) (label2) (label3)". This is annoying and abnoxious to read.
When a player clicks the atom with a hand labeler to apply a label, this component gets applied to it.
If the labeler is off, the component will be removed from it, and the label will be removed from its name.
