Added
* Added a modification to the handling of ModelResource.serial_fields to enable a dictionary of a foreign class and serial fields to be returned when replacing the current Model class with another on responses.
* Added Parent/Child processing in POST. This enables the creation of child records as part of the commit process of a parent.
* Added an example program creating an invoice with invoice line items at the same time.
Changed
* Corrected approach for default URLs for meta resources. Now the generation of the default URL stems from the root of the model resource.
For example, if the model resource URL is:
/products
then the meta resources URLs will be
/meta/products/single
/meta/products/collection
However if the prefix for products is changed to
/api/v1/products
then the meta resources URLs will be
/api/v1/meta/products/single or
/api/v1/meta/products/collection
