de-select keys (feature request)

[mbaudis]

Hi,

I suggest adding an option to filter (blacklist, optional whitelist) keys:

• -exclude_keys _id

... or such. Helpful if one wants to represent the "content related" parts of a schema.

@mbaudis oh yes! I need that feature too. Will add it soon

(btw, PRs are highly welcome!)
