In series mode, dicomtocsv doesn't always report value from matching file

[dgobbi]

The default behavior of dicomtocsv is to print a record for each series that matches the specified query. Each record has fields for each of the queried attributes.

The series is deemed to match if any of the files of the series is a match. However, by default, the printed value is taken from the first file in the series, even if the first file itself was not a match.

This issue can be seen by doing the following query:

dicomtocsv /path/to/directory -k InstanceNumber=16

For each series that is found, the reported instance number is 1.

This behavior could be fixed if dicomtocsv could be told to query at the IMAGE level but report results at the SERIES level. Then NumberOfReferences would then be the number of matching images, rather than the total number of images in the series.

I don't think that I want to have a separate "reporting" level and "query" level, at least not yet. Perhaps I can do this if I create a new tool with a new interface.
