Initial work for Holiday Inn

- Selectors not specific enough; need more granularity
- Need to get correct paths for Holiday Inn; so close!
Added *mostly* working HolidayInn

- It looks like this should work for many Holiday Inn instances
- Still need the group code, and a bit of verification on a non-AN date
Corrected hotel selector
Made change to support multiple Holiday Inn hotels

- Still need convention code >_<
Added group code for Holiday Inn International

- Still need to contact Airport - East for code...
Removed improper comments
Merge pull request #2 from nt3rp/holiday-inn
