/**
 * Logged in players always have exactly one FPlayer instance.
 * Logged out players may or may not have an FPlayer instance. They will always have one if they are part of a faction.
 * This is because only players with a faction are saved to disk (in order to not waste disk space).
 * 
 * The FPlayer is linked to a minecraft player using the player name.
 * 
 * The same instance is always returned for the same player.
 * This means you can use the == operator. No .equals method necessary.
