Adding variable description in DataFrame
Hi,

I think it would be great if DataFrame is able to store additional property (list of strings) which contains the description for each variable (column). And then it can be shown by themselves with variable names as well as in the output of pandas.DataFrame.info(). I think with this DataFrame will be pretty much self contained. Right now I need to keep additional object or a text file which contains those descriptions.

Please let me know what do you think!
