Title: Topic/tiled raster data testing

This pull request transforms tiled raster data into a lean, mean, raster processing machine.

It includes examples of raster operations which will correctly parallelize across tiles, as well as examples of map/reduce type operations. It fixes laziness for the different tiled raster data, and shows that the parallelization is good enough that we can operate on tile sets on disk without major penalties.
