[Insight-developers] Adding ValueType to itk::Image

[Jisung Kim]

Hi.

It seems like adding ValueType to image is okay with
folks. 

However,I think there are two data element types in 
PoinSet, PointType and PixelType (PointData) referred
by common identifier (PointIdentifier). The former is
stored in the PointContainer and the latter in
PointDataContainer.

Up to now, in term of statistics, I ignored the
PointData and considered the points in a PointSet
exist in feature space. In this case, the ValueType
should be PointType. I don't know the answer about
which data is primary in PointSet.

Thanks,

Jisung.
