Simple tools for container iteration (library)

iter and its sub-packages provide a set of utilities to make it easy for providers of objects that are iteratable.

For example, if your object is map-like and you want a way for users to iterate through all or specific keys in your object, all you need to do is to provide a function that iterates through the pairs that you want, and send them to a channel.

Then you create an iterator from the channel, and pass the iterator to the user. The user can then safely iterate through all elements.
