 * Creates a HUD synchronization object.  This object is used to automatically assign and

 * different channels can overlap, but text on the same channel will
 * erase the old text first.  This overlapping and overwriting gets problematic.
 *
 * A HUD synchronization object automatically selects channels for you based on
 * the following heuristics:
 *  - If channel X was last used by the object, and hasn't been modified again,
 *    channel X gets re-used.
 *  - Otherwise, a new channel is chosen based on the least-recently-used channel.
 *
 * This ensures that if you display text on a sync object, that the previous text
 * displayed on it will always be cleared first.  This is because your new text
 * will either overwrite the old text on the same channel, or because another
 * channel has already erased your text.
 *
 * Note that messages can still overlap if they are on different synchronization
 * objects, or they are displayed to manual channels.
 *
 * These are particularly useful for displaying repeating or refreshing HUD text, in
 * addition to displaying multiple message sets in one area of the screen (for example,
 * center-say messages that may pop up randomly that you don't want to overlap each
 * other).
