* \brief Base class for filters that take both a path and an image as input and produce a path as output.
*
* This class is the base class for filters that take both a path and an image
* as input and produce a path as output. Specifically, this class defines the
* methods SetPathInput() and SetImageInput(). (It also establishes the
* precedent of having path inputs precede image inputs for functions producing
* paths as outputs, according to the underlying DataObject implementation.)
