ANN_MLP GetParams returns default values

ANN_MLP::Params params = m_classifier->getParams(); 
returns default params, even m_classifier is already loaded

layers size is not being retrived correctly you should consider to add on "ann_mlp.cpp" function "void read( const FileNode& fn )" something like:

params.layerSizes = Mat_<int>(_layer_sizes, true); 

after read_params(fn);

Can not reproduce with the latest master branch:

<pre>
Ptr<ANN_MLP> ann = ANN_MLP::create();
ann->setLayerSizes(layer_sizes);
ann->save(fname);
cout << "Set " << ann->getLayerSizes() << endl;

Ptr<ANN_MLP> new_ann = Algorithm::load<ANN_MLP>(fname);
cout << "Get " << new_ann->getLayerSizes() << endl;
</pre>
Layer sizes are read correctly.

Can you, please, check it again?
