 Returns the data window. Any coordinate inside this window is safe to pass to value() in the Field subclass.

 Returns the extents of the data. This signifies the relevant area that the data exists over. However, the data window (below) may be smaller than the extents, in which case it is only safe to call value() for those coordinate inside the data window.

 This constructor ensures that we have a valid mapping at all times.

Detailed Description

This class serves to isolate the extents and data window from its templated subclasses. Thus, anything that needs to access the extents or data window don't need to know about what data type the subclass is templated on.

It also owns the field's mapping.

Why do we have both an extent and a data window? The extents are used to define which range of voxels define the [0..1] local coordinate system. The data window in turn defines the voxels that are legal to read/write from. Thus, for optimization we may have a large extents but a small data window, or a small extents and a larger data window which would let us apply large-kernel filters without having to deal with boundary conditions.
