 * Define a new internal state.

 * States should be defined when a script is started.
 *
 * @param {Integer} index
 *    The intgeger number assigned to the new state. Only numbers
 *    in the range [10, 255] are allowed.
 *
 * @param {String} [name]
 *    A short name describing the state. According the the convention
 *    used throughout FACT++, it it must not contain whitespaces or
 *    underscores. Ever word should start with a capital letter,
 *    e.g. 'TriggerOn'
 *
 * @param {String} [decription]
 *    A user defined string which gives a more conscise explanation
 *    of the meaning of the state and can also be displayed in the GUI
 *    or anywhere else automatically,
 *    e.g. "System setup and trigger switched on"
 *
 * @throws
 *    <li> if something is wrong with the supplied arguments (type, number)
 *    <li> when the index is out of range [10,255]
 *    <li> the given state name is empty
 *    <li> the given state name contains a colon or an equal sign
 *    <li> when a state with the same name or index was already

 * @returns {Boolean}
 *    A boolean whether the state was newly added (true) or an existing

 *    <li> if a String is given and it is not found in the list of names
 *
 * @returns {Boolean}
 *     A boolean is returned whether setting the state wa sucessfull or

/**
 * Set an interrupt handler, a function which is called if an
 * interrupt is received, e.g. via dim (dimctrl --interrupt).
 * Note that the interrupt handler is executed in its own JavaScript
 * thread. Thus it interrupts the execution of the script, but does
 * not stop its execution. Please also note that this is a callback
 * from the main loop. As long as the handler is executed, no other
 * event (dim or command interface) will be processed.
 *
 * If an interrupt was triggered by dimctrl (so not from within
 * the script) and a number between 10 and 255 is returned,
 * the state machine will change its state accordingly. Other returned
 * ojects or returned values outside of this range are ignored.
 *
 * @param {Function} [func]
 *    Function to be called when an interrupt is received. Null, undefined
 *    or no argument to remove the handler.
 *
 * @throws
 *    if number of type of arguments is wrong
 *
 * @example
 *     function handleIrq(irq, args, time, user)

 *     must not contain any line break.
 *
 * @param [. . .]
