Add in the ability to subscribe to a calendar feed.

Personal comment:

Love the idea of Lifestack. Energy mapping is an upgrade I'm looking to make into my app stack. There is a similar app in the Apple App Store to Lifestack. This app offers a calendar subscription to which you can subscribe to across all your calendar applications. This is a baseline requirement for me. The reasons are: I am an active Sunsama user, and, I often check my calendar on mobile apps like Google Calendar for iOS, Apple iCal and Outlook for iOS. I need the overlay available seamlessly across all devices for these two reasons. I would only return to the web app of LIfestack as part of a daily habit or routine, not as my "daily driver". The product cannot expect to compete at such an early stage with the many, many calendar offerings out there. Thus, I highly suggest allowing users to subscribe to a calendar subscription. (I did not find the events added to my calendar overwhelming when trying the app mentioned above.)
