Remarks
This is a MEF component part, and should be imported as follows:
[Import]
Internal IHierarchicalStringDifferenceService hierarchicalService = null;
Differences are computed according to the specified StringDifferenceTypes, starting with the most general type. Line is more general than word, and word is more general than character.
Examples
Given string A:
This is a
line!
and string B:
This is but a
line!
The returned difference collection contains one line difference, which maps to line 1 of each string.
This difference contains one word difference, which is the addition of the words "but" and " ".
