+with the extension purposes to be used in the [PyCaBeM](https://github.com/eXascaleInfolab/PyCABeM) clustering benchmark. The extendsion and bugfixes include: modification of the I/O, node base synchronization, NMI_sqrt added, normalization border cases fixed (the case of fully overlapping multiple clusters), etc.
