 * - salesforce_example_entity_delete (hook_entity_delete)
 *
 * In this example we are doing some work with Drupal Commerce entities,
 * specifically products (commerce_product) and product variations
 * (commerce_product_variation)
 *
 * If you're not familiar with Drupal Commerce object relationships, all you
 * need to know is that Products are umbrella entities around Product
 * Variations.  Products have Product Variatinos. So if you have a Drupal
 * T-Shirt in sizes S,M,L,XL, the Product is "Drupal T-Shirt" and you will have
 * four Product Variations, one for each size.  The Product object will have
 * entity references to each Product Variation.
