/**
* RestView that supports accepting input and deleting a resource that is missing.
*
* The RestDeleteMissingView solely exists to support a special case for creating a change edit
* by deleting a path in the non-existing change edit. This interface should not be used for new
* REST API's.
*
*
The input must be supplied as JSON as the body of the HTTP request. Delete views can be
* invoked by the HTTP method {@code DELETE}.
*
*
The RestDeleteMissingView is only invoked when the parse method of the {@code RestCollection}
* throws {@link ResourceNotFoundException}, and hence the resource doesn't exist yet.
*
* @param
type of the parent resource
* @param type of the child resource that id deleted
* @param type of input the JSON parser will parse the input into.
