Modular dicom processing

New non-trivial DICOM flows can be built using a modular system of capabilities that are mixed in as appropriate with a core class implementing a common base interface.

Tag paths

Added new data structure for tag paths. A tag path ponts to a tag or sequence in a dataset, possibly nested within other datasets. The modify flow has been updated to work with tag paths, making it possible to modify tags in sequences. Also, a bulk data filter was added.
