it seems like it could be useful functionality. plus, if you had some function `scrub_string`, making a version that scrubbed strings in objects would be as simple as:

```coffee
scrub_object = (obj) -> _.deepMapValues obj, (v) -> if _.isString v then scrub_string v else v
```

which means you could make a function to turn a string scrubber into an object scrubber:

```coffee
make_object_scrubber = (scrub_string) ->
  # ... the snippet above ...
```
