Clone Django's `View.as_view()` behaviour *except* using REST framework's
'method -> action' binding for resources.
This is the magic.
Overrides `.as_view()` so that it takes an `actions` keyword that performs
the binding of HTTP methods to actions on the Resource.
For example, to create a concrete view binding the 'GET' and 'POST' methods
to the 'list' and 'create' actions...
my_resource = MyResource.as_view({'get': 'list', 'post': 'create'})
