New PSyKE structure (from version 0.4.5)

[sabbatinif]

From version 0.4.5 GUI and students' code are only in separate branches. In the future, the GUI will be placed in a separate repository and students' code will be included in the master after a careful revision/testing.

Furthermore, package structure and interfaces have been moved/changed. In particular, the psyke package contains the following subpackages:

• extraction, for SKE techniques (cart, real, trepan, iter, gridex, gridrex, creepy);
• tuning, for automated parameter tuning (pedro, orchid, crash);
• clustering, for interpretable clustering algorithms (cream and exact).

SKE techniques based on hypercubes (iter, gridex, gridrex, creepy) can be found within extraction.hypercubic.

The __init__.py file of the psyke package contains the following interfaces:

• EvaluableModel;
• Extractor and Clustering, extending EvaluableModel;
• PedagogicalExtractor, extending Extractor.

Other interfaces are:

• HyperCubePredictor (in hypercubic/__init__.py);
• HyperCubeExtractor, extending HyperCubePredictor and PedagogicalExtractor (in hypercubic/__init__.py);
• HyperCubeClustering, (in clustering/__init__.py).
