Examples of DBCollection

com.massivecraft.mcore.xlib.mongodb.DBCollection
This class provides a skeleton implementation of a database collection.
A typical invocation sequence is thus
```
 MongoClient mongoClient = new MongoClient(new ServerAddress("localhost", 27017)); DB db = mongo.getDB("mydb"); DBCollection collection = db.getCollection("test"); 
```
