identifiable 0.2.0

Identifiable mixin and id-based collection helpers for Dart.

0.2.0

• BREAKING: Identifiable is now generic over the id type — Identifiable<I> (records, ints, etc.). Mix Identity (= Identifiable<String>) or Identifiable<String> instead of bare Identifiable.
• Add IdentifiableIterable.updateById and IdentifiableList.indexWhereById.

0.1.1

• Add hasSameId (id-only check); isSameAs now also requires a matching runtimeType.

0.1.0

• Initial release.
• Identifiable mixin (id, isSameAs).
• IdentifiableIterable: includes, overlaps, withoutId, byId, toMapById.
• IdentifiableMap: upsert, upsertAll, removeById, updateById.
