Licensing text in source files

[perib]

TPOT1 had some files with licensing text from other packages (for example: https://github.com/EpistasisLab/tpot/blob/master/tpot/builtins/one_hot_encoder.py)

Do we add those here as well?

Additionally, TPOT1 started its source files with the following text. Do we do the same in TPOT2?
