\brief Given a cursor that may represent a specialization or instantiation
of a template, retrieve the cursor that represents the template that it
specializes or from which it was instantiated.
This routine determines the template involved both for explicit
specializations of templates and for implicit instantiations of the template,
both of which are referred to as "specializations". For a class template
specialization (e.g., \c std::vector<bool>), this routine will return
either the primary template (\c std::vector) or, if the specialization was
instantiated from a class template partial specialization, the class template
partial specialization. For a class template partial specialization and a
function template specialization (including instantiations), this
this routine will return the specialized template.
For members of a class template (e.g., member functions, member classes, or
static data members), returns the specialized or instantiated member.
Although not strictly "templates" in the C++ language, members of class
templates have the same notions of specializations and instantiations that
templates do, so this routine treats them similarly.
\param C A cursor that may be a specialization of a template or a member
of a template.
\returns If the given cursor is a specialization or instantiation of a
template or a member thereof, the template or member that it specializes or
from which it was instantiated. Otherwise, returns a NULL cursor.
