DOC: splitting the IO docs into separate pages

[jorisvandenbossche]

The documentation on the extensive pandas IO tools is currently one big page: http://pandas.pydata.org/pandas-docs/stable/io.html.

I propose to split this in several files: a page with a general introduction to the IO tools, and then one page per format (writer/reader combo).
(this could be seen as a first start for #6000)

Splitting this shouldn't be that hard (I was just a bit experimenting if it would be possible to keep git blame working for all splitted files, but not that important probably ..), but an issue I would like to get some feedback for: What do we do with all existing links? How do we keep them working?

Anybody who has some experience with such issues when restructuring a website what the best way is to deal with this?

Hi @jorisvandenbossche is this still something that needs working on? It seems like the docs have changed a lot since the creation of this issue.

Hi, I'll be happy to take on this restructuration. I'll aim to split the long User Guide > I/O page (https://pandas.pydata.org/pandas-docs/stable/user_guide/io.html) as initially suggested into several pages:

• A first introductory page. => what do you think of adding Other file formats and Performance considerations sections here ?
• 20 pages, one per reader/writer combo.

I will aim to do the nesting like in the other big sections : e.g.

Let me know if this is still relevant.
