/*
 * geounits.h -- Schema for the GEO_UNITS class used by Sequoia.
 *
 *	There's a tuple in GEO_UNITS for every georeferenced coordinate
 *	system (that is, projection) that we use.  We can express
 *	geo-referenced coordinates in any of these projections, and the
 *	code will keep the different projections straight and guarantee
 *	commensurability.
