This class allows for parsing and editing of configuration datasources. Do not use this class only to read datasources because of the overhead it creates to keep track of the configuration structure.
Constructor Initializes a container and returns its root element.
Requires the type of data container. If the container needs special parameters upon initialization, set them in $options. The format and required content of object 'datasrc' depend on the chosen container.
Return: PEAR_Error on error or container root element
