* Changes for WTI-Review-469: ** Renamed IComment to ICommentable and updates XML docs. ** ICommentContext and CommentView do not have IAssessmentSection properties any more. Instead RingtoetsGuiPlugin view-closure code has been improved. *** Also fixed bug: Deleting a piping calculation group now does properly close an open CommentView for any child calculation at any depth. *** Improved test coverage for closing CommentView for various data. ** Some cleanup *** Reformatted code to reduce long lines of code. *** Reordered lines of code to improve code coherence. *** Not making mocks of simple objects, neither of IDisposable concrete objects. *** Closure of MockRepositories with VerifyAll methods.
