 EXPERIMENTAL. For now, this is meant to be used by the solver and not filled
 by clients.

 Hold symmetry information about the set of feasible solutions. If we permute
 the variable values of any feasible solution using one of the permutation
 described here, we should always get another feasible solution.

 We usually also enforce that the objective of the new solution is the same.

 The group of permutations encoded here is usually computed from the encoding
 of the model, so it is not meant to be a complete representation of the
 feasible solution symmetries, just a valid subgroup.

getOrbitopesList

public java.util.List<DenseMatrixProto> getOrbitopesList()

 An orbitope is a special symmetry structure of the solution space. If the
 variable indices are arranged in a matrix (with no duplicates), then any
 permutation of the columns will be a valid permutation of the feasible
 space.

 This arise quite often. The typical example is a graph coloring problem
 where for each node i, you have j booleans to indicate its color. If the
 variables color_of_i_is_j are arranged in a matrix[i][j], then any columns
 permutations leave the problem invariant.
