* Call `hud.register_hudbar` to make the definition of the HUD bar known to this mod
* Call `hud.hudbars[identifier].add_all` for each player for which you want to use previously defined HUD bar
* Call `hud.init_hudbar` for each player for which you want to use previously defined HUD bar
* Use `hud.change_hudbar` whenever you need to change the values of a HUD bar of a certain player

You probably want to do this in the `minetest.register_on_joinplayer`.
### `hud.hudtables[identifier].add_all(player, start_value, start_max)`
This function activates and displays
### `hud.init_hudbar(player, identifier, start_value, start_max)`
This function initialzed and activates a previously registered HUD bar and assigns it to a
certain client. This has only to be done once per player and after that, you can change
the values using `hud.change_hudbar`.
However, if `start_hide` was set to `true` for the HUD bar, the HUD bar will initially be hidden, but
the HUD elements are still sent to the client.
You have to replace `identifier` with the identifier string you have specified previously, i.e. use
`hud.hudtables["example"].add_all` if your identifier string is `"example"`. The identifier
specifies the type of HUD bar you want to display.
This is admittedly a rather odd function call and will likely to be changed.
However, if `start_hide` was set to `true` for the HUD bar (in `hud.register_hudbar`), the HUD bar
will initially be hidden, but the HUD elements are still sent to the client. Otherwise,
the HUD bar will be initially be shown to the player.
#### Parameters
* `player`: `ObjectRef` of the player to which the new HUD bar should be displayed to.
* `identifier`: The identifier of the HUD bar type, as specified in `hud.register_hudbar`.
* `start_value`: The initial current value of the HUD bar. This is optional, `default_start_value` of the registration function will be used, if this is `nil`.
* `start_max`: The initial maximum value of the HUD bar. This is optional, `default_start_max` of the registration function will be used, if this is `nil`

After a HUD bar has been added, you can change the current and maximum value on a per-player basis.
You use the function `hud.change_hudbar` for this.

#### Parameters
* `player`: `ObjectRef` of the player to which the HUD bar belongs to
* `hudtable`: The table containing the HUD bar definition. Specify as `hud.hudtables[identifier]`, i.e. if your identifier was `example`, then you use `hud.hudtables["example"]`.

Note that the hidden state of a HUD bar will *not* be saved by this mod on server shutdown, so you may need
to write your own routines for this.
### `hud.hide_hudbar(player, hudtable)`
### `hud.hide_hudbar(player, identifier)`
Hides the specified HUD bar from the screen of the specified player.
