/**
 * Yields each taxonomy term in the Categories column.
 *
 * The cell containing the WooCommerce 3 categories is a comma separated list of
 * the categories assigned to the product variation in this row. Each category
 * is a string of categories with a greater than sign delimiter. The term on the
 * left of the > is the parent of the term on the right side. The depth of the
 * hierarchy is increased by adding '> child' strings, as many as is needed.
 *
 * Example:
 * @code
 * Clothing > Hoodies, Clothing > Hoodies > Pocket, Clothing > Hoodies > Zip
 * @endcode
 * In this case, the term 'Clothing' is the parent of 'Hoodies' which is the
 * parent of 'Pocket' and the parent of 'Zip'.
