Initial release

This is the first release of the project that also includes the quasi publication of the implemented local clustering algorithms.

Contents:

• The algorithms.rst in the documents folder contains the description (sort of a base publication) of the Hermina-Janos local clustering algorithm this library implements.
• The code in the library implements the aforementioned clustering algorithm accompanied by utilities for node ranking and algorithm step tracking.
• A demo is also included that shows the basic usage of the cluster engines and the ranking module.
