Requires at least the following section is the .ggo file

option "interp"		-	"Interpolation: 0=NN, 1=Linear, 2=BSpline, 3=BLUT"	int  	no  default="1"
option "interpOrder"	-	"Order if BLUT or BSpline (0-5)"		        int  	no  default="3"
option "interpSF"	-	"Sampling factor if BLUT"			        int  	no  default="20"

The use will look something like

typedef clitk::GenericInterpolator<InputImageType, double> GenericInterpolatorType;
typename GenericInterpolatorType::Pointer genericInterpolator=GenericInterpolatorType::New();
genericInterpolator->SetArgsInfo(m_ArgsInfo);
typedef itk::InterpolateImageFunction<InputImageType, double> InterpolatorType;
typename InterpolatorType::Pointer interpolator=genericInterpolator->GetInterpolatorPointer();
