* Usage:
*
* R::addDatabase( 'database-1', 'sqlite:/tmp/db1.txt' );
* R::selectDatabase( 'database-1' ); //to select database again
*
* This method allows you to dynamically add (and select) new databases
* to the facade. Adding a database with the same key will cause an exception.

* @param string $dsn DSN for the database
* @param string $user user for connection
