problem in windows

renameDataset.sh can't run in windows.

please create a renameDataset..bat to renameDataset.

Lean use C#, we use Visual studio.

1. Use a Python script instead of a bash script, because it works in every platform
2. The script should delete universe files if the dataset doesn't provide universe data. Then we can delete this sentence:

If your dataset doesn't provide universe data, delete the Lean.DataSource. / Universe.cs file and skip this part.

The script should also delete the universe files from Tests.csproj
