What's new in this version:
Improved USGS DEM exporter to conform to specification. The old version of the exporter is still available under the File menu as "USGS ASCII chop" in case it is needed for compatability with old software. Fixed error reading and writing datum information. Updated Arc importers to allow DOS, Unix, and Mac line endings in text files. Also allow GridFloat file names to end in .bin in addition to .flt
