Use new signature for import_ceos()
First pass at ROI2IMG with position information
Merge branch 'master' of github.com:talogan/ASF_MapReady
Merge branch 'master' of github.com:khogenso/ASF_MapReady
Better handling of truncated files.

If the metadata says the file should be 1000 lines but we calculate from
the file size that it looks to be only 800 lines long, change the line
count to 800 before reading in the data.
New option for roi2img that only generates a metadata file (no .img)
First cut for implementing ISO metadata:
- defined ISO metadata structure
- mapped old metadata structure to ISO
- implemented reading/writing functions to ISO XML file
Merge branch 'master' of github.com:rudigens/ASF_MapReady
Forgot one file for previous check in.
Added two more fields to the metadata structure:
- receiving station
- heading angle

Makes it easier to populate the new ISO metadata structure later.
Removing built files.
Implemented the writing of ISO metadata into HDF5 file.
All changes related to generating ISO metadata and writing that structure into HDF5 files.
Forgot to check in the XML schema. This will need to be copied to the location of wherever the XML is generated. Haven't written that part yet, as I focused on the generation of products first.
Implemented a function to write ISO metadata into ISO standard structure (including namespaces).
Updated the writing of the ISO metadata XML file, so that the structure validates against the XML schema (currently only without the namespaces).
Implemented a tool for the conversion of RGPS MEASURES lagrangian products into CSV files.
Minor edits.
Newest version of create_roi_in & roi2img
also fixed int/double bug in sr2gr
:
I am so confused.  I think that I'm checking in sr2gr.c (bug fix) and roi2img.c,
but I have no idea why they weren't already checked in or why I have to do this
again.
