/** \class TensorVolumePatch
 * \ingroup CXX11_Tensor_Module
 *
 * \brief Patch extraction specialized for processing of volumetric data.
 * This assumes that the input has a least 4 dimensions ordered as follows:
 *  - channels
 *  - planes
 *  - rows
 *  - columns
 *  - (optional) additional dimensions such as time or batch size.
 * Calling the volume patch code with patch_planes, patch_rows, and patch_cols
 * is equivalent to calling the regular patch extraction code with parameters
 * d, patch_planes, patch_rows, patch_cols, and 1 for all the additional
 * dimensions.
