Future Development Ideas

• Use the cards concept to make more rich interactions with the Bot.
• Interactions with Nestmon, some Go code I wrote to stream Nest thermostat updates from my house. First just a way to see the current cooling/heating status of my home. Eventually maybe some sort of write capabilities to modify temperatures inside my home.
