*
* @brief Abstract interface for the instrument direction of an event.
*
* The instrument direction of an event is the equivalent of the sky
* direction (implemented by GSkyDir) but in the instrument data space.
* The instrument direction may be any kind of position or direction
* information encoded in the data space, such as incident event
* reconstructions for imaging devices or detector numbers etc. for
* non-imaging devices.
