This test compares all KeyTemplates (available via {@code KeyTemplates.get("SomeString")} to
corresponding parameters objects.

<p>This can be used to find {@link Parameters} object which correspond to results of {@code
KeyTemplates.get(s)} for a given string {@code s}: simply check the list in {@code TEMPLATES}
below: if a pair {@code (s,p)} is in this list, this means that {@code
KeyTemplates.get(s).toParameters()} is equal to {@code p}.
