Produce a rasterly object and return the raster information required to produce an image

rasterly_build(rastObj)

Arguments

rastObj	A rasterly object. It should be a list of environments composed of a rasterly() and several rasterly_... layers.

Note

A rasterly object will never be produced until rasterly_build() is called.
