Scala classes to allow more elegant use of Multiverse from Scala. Atm the functionality is quite limited since not a lot of effort was put in the Scala integration. For the 0.6 release Multiverse should be able to work with in Scala written transactional objects configured with the Multiverse annotations. So that would reduce the need for this library, although in Scala they want to have special Scala 'interfaces' that provide some syntactic sugar to use java collections in Scala. So this module would be the good location for that. If anyone would like to help improving the Multiverse/Scala integration, please don't hesitate to join.
