// NameTagToggle.cs
// A /nametags chat command that turns player name tags on or off in this world.
//
//   /nametags off              hide every player's name tag
//   /nametags on               show them again
//   /nametags off <username>   hide one player's tag (for everyone)
//   /nametags on  <username>   show that one player's tag again
//
// A name tag is the floating username shown when you hover, tap or point at a player. This overrides the
// scene's "Show player name tags" setting for the current world only; leaving the world clears it.
