/*
History:
* 2007/05/18: initial release (only a reader)
* 2007/05/20: added writer code with embedded bitmap
* 2007/05/22: add support for multiple bounding boxes
(useful / required!) for large waypoints lists
* 2007/05/23: add optional user bitmap
* 2007/06/02: new method to compute center (mean) of bounds
avoid endless loop in group splitting
* 2007/07/10: put address fields (i.e. city) into GMSD
* 2007/07/12: add write support for new address fields
* 2007/10/20: add option unique
* 2007/12/02: support speed and proximity distance (+ alerts)
* 2008/01/14: fix structure error after adding speed/proximity
* 2008/03/22: add options "speed" and "proximity" (default values) and "sleep"
ToDo:
* Display mode ("Symbol & Name") ??? not in gpi ???
* support category from GMSD "Garmin Special Data"
