[Insight-developers] Re: Meta data dictionary passing through the ITK pipeline

[Douglas Alan]

Hi, Jim -- enclosed is a set of diffs for the changes you made to
Slicer3 at NA-MIC Programming Week that provide for propagation of an
input file's MetaDataDictionary to a MRML node.  Thanks muchly for your
help in getting us past this roadblock!
