organize data according to scalar span space
This is a helper class used to accelerate contouring operations. Given an dataset, it organizes the dataset cells into a 2D binned space, with axes (scalar_min,scalar_max). This so-called span space can then be traversed quickly to find the cells that intersect a particular contour value.
This class has an API that supports both serial and parallel operation. The parallel API enables the using class to grab arrays (or batches) of cells that lie along a particular row in the span space. These arrays can then be processed separately in parallel.
Learn more about span space in these two publications: 1) "A Near
Optimal Isosorface Extraction Algorithm Using the Spsn Space." Yarden Livnat et al. and 2) Isosurfacing in SPan Space with Utmost Efficiency." Han-Wei Shen et al.
