Implemented a new tool 'smap2browse' to generate a series of browse images, including world and auxiliary file, from a SMAP HDF5 file.

meta_get_latLon needed some work to return correct sub-pixel values (bilinear interpolation). I took out any special cases for meta_get_lineSamp and geocoding. Everything works now with established functionality.

Did some clean up for compiler warnings.
