Generate classifier with annotation processing

[richardstartin]

Currently attributes used for classification are registered separately from the definition of the classified objects. It should be possible to annotate methods and generate a classifier from the definition. This could include simple functionality like scaling values.

The code below would generate a classifier with a weight attribute.

class ToBeClassified {

@Classifiable(scale = 0.5)
public double getWeight() {
...
}

}
