Description

Determines whether there is some sub-sequence within [begin,end) that matches the regular expression re.

Parameters:

`begin`	The beginning of the sequence
`end`	The end of the sequence
`flags`	Optional match flags, used to control how the expression is matched against the sequence. (See match_flag_type.)
`re`	The regular expression object to use
`what`	The match_results struct into which the sub_matches will be written

Requires:

Types BidiIter and OtherBidiIter meet the requirements of a Bidirectional Iterator (24.1.4).

OtherBidiIter is convertible to BidiIter.

[begin,end) denotes a valid iterator range.

Returns:

true if a match is found, false otherwise

Throws: regex_error on stack exhaustion
