scrape option limited by filepath expectations

[karenhaining]

Because the scrape option expects the original file to be in the same exact structure as how camp outputs files, it limits the organization of files in other repositories which rely on camp outputs.

anms-camp/src/camp/generators/create_impl_h.py

Line 43 in 1302277

scrape_src = full_path if scrape and os.path.exists(full_path) else None

For example, in the reference implementation dtnma-tools, files under src/ion_if/bpv7/adm will never get scraped correctly because they do not live under a directory named agent.

Additionally, the scrape (roundtripping) behavior as described in the README is out of date (the -c and -h flag options, which sound like desirable behavior, do not exist).
