#308: GMM initial parameter values

 I am using the GMM class with the EMFit clustering method GMM<EMFit<> >.
 I am passing initial values of means, covariances and weights, previously
 GMM<EMFit<> > ml_gmm(initial_means, initial_covariances, initail_weights);

 I thought that the Estimate function starts the EM from these values, but
 the first step is to calculate the parameters with the function

 Am I understanding it wrong? It is possible to start the EM from some
 initial values? Maybe commenting out the InitialClustering call in

 Thanks a lot,
