create seperator.sh file.

This shell script takes the data from data/lm1-exhibition-all.csv and breaks it
down into readings taken on a daily scale and then an hourly scale.

At the moment, it produces directories and files for times/days which have no
readings but I don't know if that's relevant or not. By having no data in
certain files, it does confirm 'No Data Recorded' if/when people look to review
the data and wonder why they can't find any for a particular day.
