Forked from MongoTalk (http://www.squeaksource.com/MongoTalk)
- Package organizations were refactored. 
- Removed dependencies to Grease. (MongoSt assumes Squeak/Pharo/VW default libraries only). 
- New portability layer for other dialects. 
- TestCases were refactored. 
- All classes are 'Mg' prefixed for avoid possible class name conflicts. 
- Multibyte strings/symbols are handled correctly.
