/** \class SplitAlternatingTimeSeriesImageFilter
* \brief Join N-D images into an (N+1)-D image
*
* This filter is templated over the input image type and the output image
* type. The pixel type of them must be the same and the input dimension
* must be less than the output dimension.
* When the input images are N-dimensinal, they are joined in order and
* the size of the N+1'th dimension of the output is same as the number of
* the inputs. The spacing and the origin (where the first input is placed)
* for the N+1'th dimension is specified in this filter. The output image
* informations for the first N dimensions are taken from the first input.
* Note that all the inputs should have the same information.
