Suggestions for the capture decorator

[timmeinhardt]

I have two suggestions for the capture decorator.

1. The sacred tool could provide a fail-safe post-definition helper function for decorating. This function could improve could such as this:

   from xxx import x, y, z
   ex = sacred.Experiment('foo')
   x = ex.capture(x)
   y = ex.capture(y)
   z = ex.capture(z)
   

   The helper function could handle the assignments and even take an array of input functions and
   look something like ex.post_capture([x, y, z]).

2. Decorating an entire class with capture should not only decorate the __init__ constructor but all class methods. If one only wants to decorate the constructor this could still be done by explicitly decorating it.

1. But unless you want to modify the global scope in some hacky way, you would have to do x, y, z = ex.post_capture([x, y, z]) no? And that you can almost do currently with x, y, z = map(ex.capture, [x, y, z]). So would post_capture really improve anything?
2. That usecase makes sense to me. I honestly have never tried capturing a class, but if it would work, I would also expect that behavior. So I'll mark this as a feature request.
