Erdo 1.0
Adding MPL2 license.
Added MPL2 license.
Getting lockmanagement tests working again.
Added README.md. Some renaming in API, and improvements to javadoc.
Changed open... to use... in API. Worked on javadoc.
Modification to scanning API. Unit tests run.
Lots of renaming: scan -> cursor.
Bringing javadoc up to date with Scan -> Cursor changes. Also, got rid of
OrderedMap.findAll(), because it did the same thing as OM.first().
Extended cursor testing.
Fixed OrderedMapTransactionTest: access to cursor closed by transaction end is now like access to any other closed cursor -- no special exception.
Removed some unnecessary typecasts.
Implementation of MapCursor.previous(). Pretty complete, but with no testing of the new functionality. Old tests work.
Implementation of reverse iteration is complete and unit tests pass.
Documentation and trivial code changes.
Moved default configuration settings into DefaultConfiguration.
Last few doc changes before first public release.
