xml file should be in same dir as nc file
Implemented the 'measures_hdf2csv' for ingest Eulerian products. Added some generic support for line shape files. Updated 'rgps2vector' to generate shape files for Eulerian in polar stereographic projection (appears the projection that Ron Kwok initialized the grid in). Backed out the latest change I made to the polar stereographic projection file (some verification using Ron's data showed the old definition was in fact right).
Some minor metadata changes.

No longer apply geoid correction automatically in asf_geocode for DEMs
Implemented 'measures2geotiff' tool for gridded multi-band images (.AGE, .BSH and .THK). This tool is using a new 'export_geotiff' function that exports data into a multi-band GeoTIFF file based on a file list. Some of the MEaSUREs files have 60 or 70 categories that have to be stored in as many bands. Our old functionality was not able to handle that.

Had to make some modificatios to 'measures2netcdf' as well to accommodate inconsistent header information.

Went through the 'measures2csv' conversion, since I had seen some issues with generating shapefiles from the motion and deformation CSV files. Still re-working some 'rgps_grid2cell' aspects, not ready to be checked it just yet.

Added 'measures2geotiff' tool for generating GeoTIFFs for multi-banded products and more.
Removed the generation of GeoTIFF files and associated metadata from the tool. This functionality is entirely covered by 'measures2geotiff'.
