Add Splitting Method

To add a new edge splitting method follow these steps:

1. Fork the dataset, pull the latest changes and create a new branch add-splitting-{split_name}

2. In the framework/dataloader/edge_splitter/edge_splitter.py implement a function that performs the splitting.

   • This function must return a list of edges of type t.List[t.Tuple[UserNode, ItemNode]]

3. In the same file, add the splitting method name to the list self.supported_methods.

4. Add the splitting method into split().

   • Add the method to the switch case.

   • Make sure to check if the parameters are valid. Otherwise, a ValueError must be raised.

5. Make a Pull Request on Github.
