hdlib v2.0.0

New features:

• The Vector class is now in hdlib.vector;
• hdlib.model.MLModel is now hdlib.model.classification;
• hdlib.graph.Graph is now hdlib.model.graph;
• The hdlib.parser module has been suppressed and its functions have been moved to examples/chopin2/chopin2.py;
• New hdlib.model.graph.GraphModel._error_rate and hdlib.model.graph.GraphModel._predict static methods for the estimation of the model error rate and the evaluation of a graph model in multiprocessing;
• New hdlib.model.regression.RegressionModel and hdlib.model.clustering.ClusteringModel classes for building regression and clustering models respectively;
• New examples about the classification of chemical structures and the classification of viral species via graph encoding.

Fixes:

• hdlib.model.graph.GraphModel.error_mitigation does not take into account for false positives;
• hdlib.model.graph.GraphModel.error_rate and hdlib.model.graph.GraphModel.predict now check whether an edge exist using weight-specific thresholds.
