\brief Retrieve the parent context of the given completion string.
The parent context of a completion string is the semantic parent of
the declaration (if any) that the code completion represents. For example,
a code completion for an Objective-C method would have the method's class
or protocol as its context.
\param completion_string The code completion string whose parent is
being queried.
\param kind DEPRECATED: always set to CXCursor_NotImplemented if non-NULL.
\returns The name of the completion parent, e.g., "NSObject" if
the completion string represents a method in the NSObject class.
