#mapservice(service) ⇒ String

Map service names into actual class names.

Some of the service names have changed over time and no longer match the class names that implement them. This maps them back, as well as correcting casing.

Parameters:

  • service (String) —

    User facing service name

Returns:

  • (String) —

    Internal class name for service
