--* This file is the main file for the QuestieDB library.
--* It contains the main functions for the library.
--
-- The library is split into two namespaces, Public and Private.
--* The Public namespace is the one that is returned when you call LibQuestieDB()
-- The Private namespace is the one that is used internally in the library.

--- The main public namespace for QuestieDB
