function bpc_taxonomy_commerce_bpc_get_combinations in Commerce Bulk Product Creation 7

Same name and namespace in other branches

1. 7.2 modules/bpc_taxonomy/bpc_taxonomy.module \bpc_taxonomy_commerce_bpc_get_combinations()

Implements hook_commmerce_bpc_get_combinations().

@todo: This is EXACTLY the same as the list implementation, except for three places where 'list' needs to be replaced by 'bpc_taxonomy'. Refactoring.

The Commerce BPC Taxonomy integration module enables the use of taxonomy term references in bulk creation.
