Code review comment for ~eslerm/ubuntu-cve-tracker:nvd-api-client

A few high level comments (I haven't yet actually run the code but will try that soon)

1. You should be able to use the configobj package to parse the configuration file rather than hand-parsing this (see cve_lib.py for some historical code for this)

2. Would it be possible to make the script as automagic as possible? ie. When it is run, it goes and looks for existing json and if that doesn't exist, then it does --init automatically. But if it does exist, then instead it uses the timestamp of that json to infer the --since date? You can keep both the --init and --since parameters as I can imagine they may be useful, but in general when we can infer and do-the-right-thing I think we should.

3. It might be useful to show a progressbar or similar AND perhaps show some indication when sleeping, since the currently implementation looks like it will sleep for 6 seconds each request which will take a long time - it would be good to give the user some kind of indication how long this is expected to take or to atleast show some kind of progress along the way so they don't think the script has hung - see the use of progressbar in sis-changes or check-cves for inspiration
