to data using the Expectation Maximization algorithm.  I placed the code in the o.a.c.m.optimization.fitting
package.  Gilles wonders if it would make more sense to have it in the o.a.c.m.distribution.fitting
package.  That may be true.

fits distributions.  It uses a lot of the code from o.a.c.m.distribution and none from o.a.c.m.optimization,
so that may imply that it would make sense to move it.

I am not a specialist in these area, but also feel EM would be more at
home with distributions er even statistics than in optimization.
