Is there a method in the boost library to iterate a vector of boost::tuple
objects, comparing the 1st element in the tuple of each tuple to a value
that I specify? My tuple is setup like so:

typedef boost::tuple<int, int, char const*> Tuple;
typedef std::vector<Tuple> ErrorStringMap;

ErrorStringMap mystrings = tuple_list_of
    (10, "10", "ten")
    (20, "20", "twenty")
    (30, "30", "thirty")
    (10, "10", "ten");

I want to search the vector of tuples and do something with every tuple
that has the number 10 as the first element in the tuple.
