added python script to get counts and separate one for linear regressions...

Hi Mark - Please find my python script for the counts.

It will take inputs of a folder, the city and the path to the stations file.

It will output `total_from.csv` and `total_to.csv`.

The regressions file is not doing very much at the moment. It goes through each row and each column and returns an list for the row values, and the col values. I believe this is wrong and needs one extra loop to achieve what it's meant to do.
