SliverGridRegularTileLayout class

A SliverGridLayout that uses equally sized and spaced tiles.

Rather that providing a grid with a SliverGridLayout directly, you instead provide the grid a SliverGridDelegate, which can compute a SliverGridLayout given the current SliverConstraints.

This layout is used by SliverGridDelegateWithFixedCrossAxisCount and SliverGridDelegateWithMaxCrossAxisExtent.
