[development] update hooks/APIs documentation

[Angie Byron]

Hi, Bèr.

Assuming nothing's much changed with the interface in the last couple weeks, I 
made a sample .install file for the Amazon associate tools module here:

http://drupal.org/files/issues/amazon_0.install

(I assume here you are talking about this issue: http://drupal.org/node/35924)

Hope it helps,

-Angie
