// .NAME vtkSMPMergePolyDataHelper - Utility class for merging poly data in parallel
// This class is designed as a utility class to help merging of poly data
// generated by filters that generate multiple polydata outputs and the associated
// locators. It requires that the filter uses vtkSMPMergePoints which creates
// a number of necessary data structures.

// Description:
// This is the data structure needed by the MergePolyData function.
// Each input is represented by a polydata (Input), a locator generated
// using identical binning structure (Locator) and offset structures
// for each vtkCellArray type. These offsets allow semi-random access
// to the cell arrays. They should store offsets to where cells start
// in the cell arrays. Each offset can be for 1 or more cells. The finer
// the granularity, the better the parallelism.

// Description:
// Given a vector of vtkSMPMergePolyDataHelper::InputData, it merges
// them and returns a new vtkPolyData (which needs to be deleted by the
// caller). Note that this function uses the first input as a temporary
// merging target so it will be modified in place. If you need to preserve
// it, use DeepCopy before passing to MergePolyData.
