08-21 Measurement fetching

There were no major problems today, the focus was on implementing algorithms I introduced and conceptualized earlier this week. I worked on the event loop that gets the data from various databases. It is a threaded task, so that execution time does not influence the polling rate (which would be the case with time.sleep(x)) and concurrency is possible. The next question is how I precisely will implement the measurement selection for the trilateration.
