Expand description

Trait used to generalize over IntoIterator+Copy and Iterator+Clone types. Actual used source is defined via type parameter which should implement Kind trait. There can be some problems when type implements Iterator and Copy simultaneously: since every Iterator automatically implements IntoIterator, and Copy implementation requires Clone implementation too, such type will suit both alternatives and will cause conflict until explicit Kind specified. Trait is not sealed, so any user can define own Iterable implementation.
