reference-guide: non-working code sample in 4.2. HAL-Forms | 4.2.3. A complete sample

[KlausUnger-SoftwareCraftsmen]

There is no support for .andAfford(...)

It should be imho .andAffordance(afford(...))

probably a convenience method andAfford(...) like stated would be nice

Will try to provide a PR for the doc fix

I think in the example should rather properly add the link to the createCustomer(…) method under a link relation, as that would add the affordance transparently.
