…eys codes

I did an addition of some changes that Cassey did before to ensure the availability of the code to run in my new environment, the change is saving the data loader stepping process, allowing to understand really well and restart the model without losing the previous downloading time.

Darren code is a renovated version of our previous methods that ensures flexibility and ability to run the codes in any environment. The reference for now is a code in debugging, later it would be transpose in a more suitable definition structure.
