/** \class MetaImageFunction
* \brief Concatenate results from multiple ImageFunction
*
* The MetaImageFunction class allows calling multiple ImageFunction at the same location
* and to concatenate their result into a single VariableLengthVector.
*
* In the case of ImageFunction which do not produce VariableLengthVector, one can wrap these
* function using the ImageFunctionAdaptor class, which will translate the image function output to
* a VariableLengthVector.
