futures

In this month's meetup, we'll be learning about futures (0.1).
The aim of the session is to get people who aren't familiar with futures up-to-speed, and to help users of futures deal with the common pain points.

We are going to:

• try out various futures combinators (map, for_each, filter_map, then, and_then, etc)
• create our own futures from the Futures trait
• deal with function return signatures (impl Future, or do we Box?)

The aim is to deal with streams in detail, and futures 0.3 in separate sessions later on.
