[support] New Ecommerce Product Type with Subproducts

[Fred Jones]

I have a shop which needs to have some products free shipping. I thought 
the easiest way to do this would be to copy the 'apparel' module and 
rename all instances of 'apparel' to 'freeshipper' and then just NOT 
activate my flexicharge shipping charges for that new product type.

I tried this but no subproducts are available for my freeshipper type 
products.

I have poked around on the subproducts code and I don't see what's going 
wrong. In particular I see this line:

  *                 Product types that return themselves
  * as part of the 'subproduct_types' productapi option are considered
  * to support variation-type subproducts. An example is the apparel
  * module in ecommerce/contrib.

and I indeed have (same as apparel.module):

     case 'subproduct_types':
       return array('freeshipper');

in function freeshipper_productapi

Any ideas as to what I am doing wrong? Or any solution to my basic 
problem of how to create free shipping products?

Thanks,
Fred
