+	READ ME
+To use this wrapper, you have to create a structure, which will be the subject of the MongoConnection function,
+
+
+MongoConnection returns three values; the first one is the connection session to the * mgo.Session type database, the second is  a * mgo.Database, and third will not be nil if you have got an error.
+
+
+The UseScheme function takes an mgo.Database type (the second argument returned by MongoConnection) and returns a * mgo.Collection
