Haskell Lesson 4 and Isomorphic Web Apps

We will continue our Haskell lesson series with Lyle delivering Lesson 4 on Higher-Order Programming and Type Inference from Brent Yorgey's CIS194 course (http://www.seas.upenn.edu/~cis194/spring13/lectures.html).

Then Michael Beidler will present on full-stack "isomorphic" web apps with Haskell (REST APIs in servant and GHCJS front-ends with react-flux).
