data:
- equilibria: list of the equilibrium for each slate, i.e. distribution of preferences 
by parties on the 5 nominees. In the data, each column x correspond to the 
type of the xth nominee.

- slate_indices_to_distribution: the nine possible nominees, i.e. alpha
and beta of the beta distribution for both parties.
Variable names:
* index: nominee type
* majdist: index of nominee distribution for the majority
* mindist:
* amaj: alpha parameter from the beta distribution, for the majority
when the nominee is of type "index"
* amin: alpha parameter from the beta distribution, for the minority
when the nominee is of type "index"
* bmaj: beta parameter from the beta distribution, for the majority
when the nominee is of type "index"
* bmin: beta parameter from the beta distribution, for the minority
when the nominee is of type "index"

- slate_indices: index of the slate, and the composition of the slate
in terms of nominees
Variable names:


- payoffmats: payoff arrays for the majority and the minority. The arrays
have 3 dimensions. The first is the index of the slate. The second is one
of the minority's strategy. The third is one of the majority's strategy
For the last two indices, a higher index means a more concentrated rule
Each element of the array is the payoff of the corresponding party when
the slate of nominees is the slate corresponding to the first index, 
and the two parties play according to the rules given by the last two indices
