Wonderful Life Utilities

We can define three new WL utilities to experiment with.
In WLU⁰ we clamp down to "never attend". It is the same as before: l(x_{d_n}(S)) - l(x_{d_n}(S) -1)
In WLU¹ we clamp down to "always attend". It is SUM_{d != d_n} l(x_d(S)) - l(x_d(s)-1)
In WLU^a we clamp down to the "average action" which in this case is attending with probability 1/h each night.
- SUM_d l(x_d(S)) - SUM_{d != d_n} l(x_d(S) + h/7) - l(x_{d_n}(S) - 1 + h/7)
