This commit introduces the vtkStructuredImplicitConnectivity class, intended as a lower-level helper that provides functionality for resolving situations where "gaps" are present in a distributed structured dataset. Gaps are resolved by communicating the data (growing the grid to the right) as necessary to close the gap. This situation is common with finite difference grids that are partitioned with respect to the nodes of the grid, or when some other post-processing filter, e.g., sampling the grid to reduce the resolution introduces a gap.The present implementation requires one grid per process and can deal with 2-D datasets -- XY,XZ,YZ -- as well as 3-D datasets. A test for all 2-D and 3-D cases is also added. Change-Id: I5260ce4fb5ced45434a719c8aacc2153253917a7
