-    The facet_module actually defines 5 registries with different capabilities:

-    - PlainRegistry: Basic unit definition and querying.
-                    Conversion between multiplicative units.
-
-    - NonMultiplicativeRegistry: Conversion between non multiplicative (offset) units.
-                                 (e.g. Temperature)

-    - ContextRegisty: Conversion between units with different dimensions according
