Connect to an Onpub database.

All the methods in this class which query the database use the database connection provided by the PDO object required by this constructor. Currently, Onpub only supports MySQL as a database for storing content. Therefore, when constructing the PDO object, only the PDO_MYSQL driver is supported as a PDO data source.

All the methods in this class require the Onpub schema to be installed in the PDO-connected database. The OnpubDatabase class contains methods to manage the Onpub schema. The Onpub schema can also be installed by clicking the "Install the schema" link once logged in to the Onpub web interface. The schema generally only has to be installed once per database.
