NFD

https://gerrit.named-data.net/3075 declares name_tree::Range as the return type of NameTree::fullEnumerate instead of "an unspecified type".

https://gerrit.named-data.net/3076 implements FIB iterator with boost::adaptors::transform.

https://gerrit.named-data.net/3086 implements StrategyChoice iterator with boost::adaptors::transform.

Measurements table does not have enumeration feature so I delete that part from this issue.
