Title: Make coordinate systems easier to use and deprecate fromarray

Add an 'is_coordsys' function, and allow callers to pass coordinate names into the coordinate system constructor, making them somewhat easier to use.

Replace 'fromimage' with full Image construction syntax. Why? Because it ellides past the need for the image to have a meaningful transform, and because it's not much simpler (any more) than using the AffineTransform constructor.
