v1.0.0 Alpha

Release candidate for the initial MAEC to STIX release.
You can probably replace all your `foodict.items()` calls with `foodict.iteritems()` in this module and others and get a performance bump. I noticed quite a few calls to `.items()` in other places as well. If you don't need to keep the list of key-value pairs around (assigning it to a variable), just use `iteritems()`.
