Density Surfaces
S3 class for rasterized fitted density surfaces. A Dsurface is a type of ‘mask’ with covariate(s) for the predicted density at each point.

A Dsurface will usually have been constructed with predictDsurface.
The ‘scale’ argument may be used to change the units of density from the default (animals / hectare) to animals / km^2 (scale = 100) or animals / 100km^2 (scale = 10000).
A virtual S4 class ‘Dsurface’ is defined to allow the definition of a method for the generic function raster from the raster package.
