/*
 * mbnavadjust is an interactive navigation adjustment package

 *
 * $Log: mbnavadjust_callbacks.c,v $
 * Revision 5.19  2008/12/22 08:32:52  caress
 * Added additional model view - survey vs survey rather than sequential.
 *
 * Revision 5.18  2008/10/17 07:52:44  caress
 * Check in on October 17, 2008.
 *
 * Revision 5.17  2008/09/11 20:12:43  caress
 * Checking in updates made during cruise AT15-36.
 *
 * Revision 5.16  2008/07/10 18:08:10  caress
 * Proceeding towards 5.1.1beta20.
 *
 * Revision 5.13  2008/05/16 22:42:32  caress
 * Release 5.1.1beta18 - working towards use of 3D uncertainty.
 *
 * Revision 5.12  2008/01/14 18:15:46  caress
 * Minor fixes.
 *
 * Revision 5.11  2007/05/14 06:34:11  caress
 * Many changes to mbnavadjust, including adding z offsets and 3D search grids.
 *
 * Revision 5.10  2006/06/16 19:30:58  caress
 * Check in after the Santa Monica Basin Mapping AUV Expedition.
 *

 * Version 5.0.8 beta.
 *
 * Revision 5.8  2005/06/04 04:34:06  caress
 * Added notion of "truecrossings", so it's possible to process the data while only looking at crossing tracks and ignoring overlap points.
 *
 * Revision 5.7  2004/12/02 06:34:27  caress
 * Fixes while supporting Reson 7k data.
