Each delivery provider, requires some information about the packages
that need to be sent as well as about the commodities (for commecial
invoices). Since this is needed by each provider, and the required
values are very similar, these packages and commodities can be done one
step ahead: in the base delivery module.
These new `_get` functions return a list of custom objects containing
the most important values concerning packages and commodities, and can
be called directly from the child classes.
