+// Database Adapter
+//
+// Allows you to change the underlying database.
+//
+// Adapter classes must implement the following methods:
+// * a constructor with signature (connectionString, optionsObject)
+// * connect()
+// * loadSchema()
+// * create(className, object)
+// * find(className, query, options)
+// * update(className, query, update, options)
+// * destroy(className, query, options)
+// * This list is incomplete and the database process is not fully modularized.
+//
+// Default is ExportAdapter, which uses mongo.
