Click on a commit to change the comparison rangefeat: add dictionary-like access to Table and Transaction
Add support for dictionary operations on tables and transactions:
- `table[key]`, `table[key] = record`, `del table[key]`
- `pop()`, `popitem()`, `setdefault()`, `update()`
Consolidate ReadableMixin into TableMixin which provides the full
interface for both Table and Transaction classes. Register TableMixin
as a virtual MutableMapping subclass to maintain JSONLT's sorted
iteration semantics while passing isinstance checks.
