[Bug-gnubg] Re: NiceRollerBot - python - take or drop after doubling

I've made two new methods to the gnubg module.

gnubg.cfevaluate()
- ------------------
This takes the current position and evaluates it cubeful. It returns a
tuple of the different cubeful equities similar to the arDouble array in
C. I believe it's:

Cubeful equity assuming correct doubling strategy
Cubeful equity for "No double"
Cubeful equity for "Double/Take"
Cubeful equity for "Double/Drop"

In that order.

You have tree optional arguments. a board, a cubeinfo and a evalcontext.

gnubg.findbestmove()
- --------------------
This method takes the current board and current dice to and return a
tuple of 8 elements with the best move.

Example:
In the initial position the dice rolled is 65.

|>> gnubg.findbestmove()
(24, 18, 18, 13, 0, 0, 0, 0)

There is also 4 optional arguments, a board, a cubeinfo, a evalcontaxt
and a diceroll.

(Notice that the movefilter used is the eval movefilter. There is no
argument to the function that controls this.)

I will make a binary available soon. This binary will then include both
the pruning neural net from Joseph and the two new methods.
