[ImageDM] Derived object

[CresitelloDittmar, Mark]

Small thread..
The imageDM contains a 'Derived' object which is carried over from the
Spectral model.  This object definition:

Derived:
    - SNR
    - Redshift.*
    - VarAmpl

I'd like to clarify the 'domain' for this information.  It seems rather
'Spectral" related, so I'm not sure if it needs to be included in the
generic ImageDM at all, but can see that certain types of images might want
this sort of information.
