Math::BigFloat wrappers for PGObject classes
PGObject::Type::BigFloat provides a PGObject-aware wrapper around Math::BigFloat. This can then be the basis of "double-facing" classes sitting between user interfaces and the database. Once registered (optionally in a registry, which must already exist), it grabs all NUMERIC and FLOAT types and returns these as Math::BigFloat-compatible objects.
