thetaInit: stochastic block model parameter to be sorted
outTheta: if TRUE returns the sorted stochastic block model parameter
outPerm: if TRUE returns the permutation of the blocks of the stochastic block model to provide the sorted stochastic block model parameter
Returns
according to the values of outTheta and outPerm the function returns the sorted stochastic block model parameter or the associated permutation of the blocks of the stochastic block model or a list with both of them
