* Database - DuckBrain
*
* Clase diseñada para crear y devolver una única instancia PDO (database).
* Hace uso de las siguientes constantes:
* DB_TYPE, DB_NAME, DB_HOST, DB_USER, DB_PASS
*
* Si DB_TYPE es sqlite, usará DB_NAME como el nombre del archivo sqlite.
* Además DB_USER y DB_PASS, no será necesariop que estén definidos.
