Detailed Description

Implements the IDataHandleVisitor interface Class used to explore heirarchy of nested IDataHandleHolders

• Instantiated with a specific target data object to find
• Descends heirarchy of tools, examining all data handles
• Returns a vector of tool/algorithm names that own handles to the target data
