-----
* Rename ResourceUtility to ResourceConfigurator to make its role clearer.
* Force human-friendly names for route pattern variables and view callable
parameters, e.g. /applications/{application_id}/users/{id} and
show(context, request, application_id, id)
* Remove ability to configure resource separator in resource names: it's always
'.'
* Singular resources via *add_singular_resource* directive or *singular=True*
keyword argument on *Resource* or *resource_config*
* Moved example from tests directory to root directory: used in test and useful
for documentation.
