Class GridCoveredCellInfoCollection
A collection with elements derived from type CoveredCellInfo. It implements ICoveredCellsProvider. Internally this collection maintains both a List of CoveredCellInfo and a so called pool. The pool allows immediate lookup of cell spans given a cells row and column index. The list allows looping through cell spans in the order they were added. GridCoveredCellInfoCollection assumes that there is no overlap between cell spans. For any given cell there only at most one cell span must exist.
