Currently only provides a single method to retrieve all available measurement units. `MeasureUnit::GetAvailable()` returns an enumeration similar to the other Intl classes which use `intl::Enumeration`. This approach gives us a more consistent API, because it abstracts away the internal ICU implementation, which looks up the measurement units through `UResourceBundle`. But it also means the implementation is slightly more complicated due to this additional abstraction. The default constructor was deleted because all methods are static.
