10.4 Formatting
These functions perform formatted substitution of the matched character sequences into
their target. The format specifiers and escape sequences accepted by these functions are
determined by their flags parameter as documented above.

Detailed Description
template<typename _Bi_iter, typename _Allocator = allocator<sub_match<_Bi_iter> >>class
std::match_results< _Bi_iter, _Allocator >
The results of a match or search operation.
A collection of character sequences representing the result of a regular expression match.
Storage for the collection is allocated and freed as necessary by the member functions of
class template match_results.
This class satisfies the Sequence requirements, with the exception that only the
operations defined for a const-qualified Sequence are supported.
The sub_match object stored at index 0 represents sub-expression 0, i.e. the whole match.
In this case the sub_match member matched is always true. The sub_match object stored at
index n denotes what matched the marked sub-expression n within the matched expression. If
the sub-expression n participated in a regular expression match then the sub_match member
matched evaluates to true, and members first and second denote the range of characters
[first, second) which formed that match. Otherwise matched is false, and members first and
second point to the end of the sequence that was searched.
