/**

* This class implements a bridge for http://www.instructables.com, supporting
|
|
* general feeds and feeds by category.
|
|
*
|
|
* Remarks:
|
|
* - For some reason it is very important to have the category URI end with a
|
|
* slash, otherwise the site defaults to the main category (i.e. Technology)!
|
|
* If you need to update the categories list, enable the 'listCategories'
|
|
* function (see comments below) and run the bridge with format=Html (see page
|
|
* source)
