/** \class ShapeSignedDistanceFunction
* \brief Base class for functions which evaluates the signed distance
* from a shape.
*
* ShapeSignedDistanceFunction is the base class for functions which
* returns the signed distance from a shape at an arbitrary point.
* A shape assumed to be defined by a set of shape and pose parameters.
*
* Note that Initialize() must be called before use.
* This allows the class an opportunity to validate any inputs.
*
* This class is templated over the coordinate representation type
* (e.g. float or double) and the space dimension.
*
* ShapeSignedDistanceFunction is used to encapsulate the shape prior
* in ShapePriorSegmentationLevelSetFunctions.
