Luke Faraone f2f4a2f8bd Move the API into a subdirectory for ease of imports.
Previously, if users of our code put the API folder in their pyshared
they would have to import it as "humbug.humbug". By moving Humbug's API
into a directory named "humbug" and moving the API into __init__, you
can just "import humbug".

Send yourself reminders on Humbug of Google Calendar events.
To get the calendar URL:
- Load Google Calendar in a web browser
- Find your calendar in the "My calendars" list on the left
- Click the down-wedge icon that appears on mouseover, and select "Calendar settings"
- Copy the link address for the "XML" button under "Private Address"
Run this on your personal machine. Your API key and calendar URL are revealed to local
users through the command line.
