Add scalaxy optimized loop benchmark.
Move jetty service to server subproject.
Increased Unit Test coverage against local operations.

- Fixed some bugs.
- Moving tests out of int.scala to their proper place.
- Made Double versions of the covered operations if they needed it.
Clean up whitespace.
Clarify task descriptions.
Add option for output raster data type (including bit).
Add isTiled() method for run-time test if a raster is tiled.

At the moment, we rely on a run-time pattern match on a raster's
data to determine if a raster's underlying data is tiled or not.

The isTiled() method allows us to do that without reflection.
Use isTiled instead of pattern matching on RasterData type.
Use isTiled() isntead of pattern matching on type.
