This is a module that provides access to EJDB, an embedded
document-centric database. For information about EJDB, visit
http://www.ejdb.org/.

NOTE: the EJDB library enforces a single instance per database per thread, so if you try to
create a database object using the same path in the same thread, you'll get an exception.
Making sure that the database and associated collection objects are destroyed helps to 
avoid this problem.

 object q = Database.EJDB.Database("foo2z", Database.EJDB.JBOWRITER|Database.EJDB.JBOCREAT);
 object c  = q->create_collection("bar");                                                   
 c->save((["name": "Tom", "age": 21]));     
  (4) Result: "5124476aeec9bd2400000003"
 c->save((["name": "Richard", "age": 32]));
  (5) Result: "51244771eec9bd2400000004"
 c->save((["name": "Harry", "age": 14]));  
  (6) Result: "51244779eec9bd2400000005"
 c->find((["name": "Tom"]));
  (7) Result: ({ /* 1 element */
                ([ /* 3 elements */
                  "_id": ObjectId(5124476aeec9bd2400000003),
                  "age": 21,
                  "name": "Tom"
                ])
            })
