* added variant_collection
* added variant_collection
* avoided &* on null pointers
* made (non-public) fixed_variant ctor explicit
* tested higher-arity visit
* implemented visit<void>
* fixed {boost::variant2|std}::variant insertion
* fixed lookup issues with invoke_visit
* removed unneeded constexpr qualifiers
* s/typeid_/index
* reverted c6bc62f6d2 as Clang 5.0 didnt seem to like it
* reinstated c6bc62f6d2
* dropped -std=c++1z for Clang 5.0
* updated docs and examples
* added boost::poly_collection::visit_by_index
* typo
* explicit cted tuple in make_iota_tuple
* changed function name to see if it helps with mangling-related Clang 3.8 ICE
* rewritten make_iota_tuple to try to make Clang 3.8 happier
* added boost::variant_collection_of
