E-M algorithm (gmix_step.m)

The E-M algorithm is explained in section 13.2.4. The calling syntax for software/gmix_step.m is as follows:
    [gparm,Q] = gmix_step(gparm,x, [bias],[data_wts]);
where gparm are the input parameters, x is the normalized input data, bias (optional) is set to 1 for BIAS method and 0 for CONSTRAINT method, and data_wts (optional) allows individually weighting input data. On return, Q is the total log-likelihood.
