Task #3738
Updated by Junxiao Shi over 8 years ago
`Fib::const_iterator` `Measurements::const_iterator` `StrategyChoice::const_iterator` are adaptors of `name_tree::Iterator`.
They can be simplified with [`boost::adaptors::transform`](http://www.boost.org/doc/libs/1_54_0/libs/range/doc/html/range/reference/adaptors/reference/transformed.html).
