The following changes were made from 0.21.
- Added support for DaffodilDB and H2 (www.h2database.com)
- For number type fields, previously, the precision was always the
maximum allowed by the destination database. A new mechanism was
added to allow the source database precision to be used if it
doesn't exceed the destination database's maximum precision.
Otherwise the previous behavior (maximum precision allowed by the
destination database) is used.
