[ESS] ESS code-folding?

[Karlo Guidoni Martins]

With that code snippet:
### acts as the first level of the folding, #### as second level and so on.

Check out if the outline-minor-mode is activated after evaluating that code
snippet as well. The TAB key open and close the folding by default, just
like org-mode.

In my case, this works like this:

Without code folding
### test1
test1 = c(1, 2)
#### test2
test2 = c(1, 2)

With code folding
### test1...
#### test2...
