 * 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

 * <p/>
 * The FPlayer is linked to a minecraft player using the player name.
 * <p/>
 * The same instance is always returned for the same player. This means you can use the == operator. No .equals method
