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.

Gets a sub_match reference for the match or submatch. Parameters:
sub indicates the submatch.
This function gets a reference to the indicated submatch, or the entire
match if sub is zero.
If sub >= size() then this function returns a sub_match with a special
value indicating no submatch.

This function returns the offset from the beginning of the target
sequence to the beginning of the submatch, unless the value of sub is
zero (the default), in which case this function returns the offset from
the beginning of the target sequence to the beginning of the match.
