Detailed Description

Use different target metrics for surface and volume elements.

This class can be used to set up a quality metric for which the target metric is different for surface elements than the one used for volume elements. It is typicallly used to set up an optimization using target metrics that aren't implemented for both topological dimemensions of elements.
