Sort out references for all models.

I will add some references.

I have put the references here. Should I put them in the code directly or do you want to put them by yourself??
How many references do you want for each model?

@ajarifi
Thank you. 1 or 2 references are enough. I have not yet decided where to write the reference. I think it should be contained in the source code (docstrings).
