Add documentation how to implement printing for a subclass

[krlmlr]

Issues to cover:

• Add information to header
• Hide row numbers
• Hide data type / use other information
• Adapt footer

Improve API along the way, also in pillar.

[krlmlr]

Also mention the fastest and safest way to construct a tibble: new_tibble(list(...), nrow = ...). (#350) (Covered in #275.)

[krlmlr]

Closing in favor of #275.

[krlmlr]

No, #275 is actually separate.

[krlmlr]

Link to the "extending" vignette already available from ?formatting.

Maybe I'm missing something, but it seems to me this has been closed and then forgotten, along with issues it supposedly subsumes. I don't see how the referenced vignette describes how to accomplish the objectives of #170 , for example.

Thanks. Can you please open a new self-contained issue and describe what's missing in the documentation?
