Added automatic gene labeling & reformatting of notebooks
A few changes:
- Added automatic gene labeling based on species given
- Update of tests for utilities and marker genes modules
- Changes to the notebooks to make it more clear where to input data
- Started formatting notebook 3 to get ready for PCA/batch correction options
I branched this from one of the other pull requests, so I think we should just merge those before this one :-)
