API: pandas is changing _propogate_attributes

[jreback]

see here: pandas-dev/pandas#5205

now going to be called __finalize__, and data is now _metadata.
and going to called on pretty much everything before returning to the user.

I am thinking about allowing this:

def __finalize__(self, other, method=None, **kwargs):
....

so that in theory a sub-class (as you guys have done), could dispatch on the method (if you need/want).

does this help?

@jreback Thanks for the heads-up. That sounds useful, and a bit more like an official API; a lot like numpy's __array_finalize__, in fact.

yep thats where it is modeled from

should be merged in shortly

Closing, addressed in #49.
