 - Create a ` method.py` and make a `Method` class that inherits from `from semb.methods import BaseMethod` and implement the required methods. See `semb/methods/node2vec/method.py` for more details.
   - Please make sure that your implemented method accepts `networkx.classes.graph.Graph` as input.

 - Install the package via `setup.py` or pip.
 - Now the method is load-able by the main client program that uses `semb`!
