Pre-Release of the Flusshygiene App "Version 2018"

The scripts written by Wolfgang Seis and running since 2018 on KWB's R server have been reviewed by Hauke Sonnenberg, refactored and put into this R package. This is a pre-release intended to be run for a certain test period. We will switch to version 1.0.0 once this version has been approved.
