Support variadic template parameters

[gnzlbg]

Example code (copy paste into a file and run cldoc on it, works as is):

#include <type_traits>

template <class... Ts> struct list;

// A list of types <Ts...>
//
// @Ts... types in the list
template <class... Ts> struct list
{
    // @return size of the list
    static constexpr std::size_t size() { return sizeof...(Ts); }
};

This generates the following documentation:

Structures

list<Ts, Ts> // A list of types <Ts...>

Then when clicking on list:

Struct list<Ts, Ts>
A list of types <Ts...>

Template Parameters
Ts
Ts

Member Functions

static
size_t
size ( )
Size of the list
return
size of the list

The following is (in my opinion) wrong (each of these should be a separate issue):

• It should be list<Ts...>,
• the reference for <Ts...> in the comment should work
• the documentation for the template parameter pack should work
• constexpr is not documented, IMO the cleanest is to just present the function signature as is:

  static constexpr size_t size();

Confirmed in latest master.

Template parameter packs are not displayed as parameter packs, but are duplicated, e.g.

template <typename ... Ts>
struct TypeList;

is documented as

Struct TypeList<Types, Types>

...actually, the duplication seems to be more general than this. Will file or update a separate issue.
