Fix to io.LoadTile for loading raster extent
Changed raster loading by name to accept data store name.

- If a layer is requested by only name (no data store name specified) and there is more than one data store that has a raster layer by that name an exception is thrown saying so.

Same name different ds
Changed how 'Context' was being used.

Context was simply functionality for operations to load layers. I moved the responsibility of owning a context away from the _run function of operations (since the large majority of ops were not using it). Now if an operation needs to load a layer it can return a LayerResult which takes a function that, given a LayerLoader (what was the Context) will give a final result.

Got rid of junit.

Brought in the GeoTrellis object from the server project to Core.

Renamed get -> run and run -> get. This is how it was in the GeoTrellis object, and I think it makes more sense...from a 'run' you get a 'OperationResult' (was CalculationResult), but if you simply call 'get' on the operation or data source you get the bare result (with an exception thrown if there is an error).
Fixed up other projects.
Changed getting tiles by name and Optio[String] store to LayerId case class.

This is in the mix of a project reshuffle.
