GET request: Renders and returns a site showing harmonization options.
POST request: Gets the harmonization options from the user and creates an object of the HarmonizeOptions class
which holds the user's chosen and default options. The harmonize_datasets function from the OSMDeviationfinder class
is called with the HarmonizeOptions object as parameter. The harmonize_datasets function uses 'yield' to return the
