ENH: DataFrame.name

[seth-p]

Currently Series has a name member, which is useful for retaining the name of the sliced index/column when the Series is produced by slicing a DataFrame.

It would be useful for DataFrame similarly to have a name member, so that when a DataFrame is produced by slicing a Panel, the name of the sliced index is retained.

And while you're at it, may as well add name to Panel and even Panel4D...

This is technically very easy to do (just add the attribute when its finalized).
BUT its actually really complicated because of how/when to propogate.

E.g.

df_a + df_b should be what? (for the name)
(and their are myriad operations like this)

Sorry about the duplicate issue...

I would think one could address these issues for DataFrames the same way they're addressed for Series... Anyway, count me as one additional vote in favor.

well after u read thru all that

it IS very easy to add
just need to propogate correctly

it's doable

I think it's a bit outside my zone of competence, though I might take a look at it if I get bored...
