Added implementation for Range gt and ge operators
...
Using a common implementation for all the operators. Note that lt is the
one used by sort so it's nice it's the fastest.

Provide a stable and consistent sort order for Range objects.
...
This matches postgres server-side behaviour and helps client applications that need to sort based on the primary key of tables where the primary key is or contains a range.

Fixed search of types into schemas.
...
We don't need to look for stuff implicitly into pg_catalog as all
the builtin ranges are already registered. So just search into
'public' if the schema is not specified.

Dropped Range._empty attribute

We can do with just _bounds: it will make eq and hash easier to
implement in a consistent way

NumberRange renamed to NumericRange
...
I was avoiding Numeric to avoid conflicting with the 'numeric'
Postgres type, which is an alias for 'decimal'. But now that there
is a single numeric range I can use the preferred name
