Basic Classifier board
In current Audiveris, the basic classifier is a Glyph classifier.
If a glyph is selected by whatever means, it is submitted to the classifier and the top 5 shapes are displayed as active buttons, by decreasing grade value.
Notice that the sum of grade values may exceed 1.0 (because no SoftMax filter is applied).
A simple click on a shape button assigns the related shape to the glyph at hand. (To be strictly correct, an Inter instance is created with proper shape and glyph).
