Returns a {@code Set} containing all the given {@code Iterable}'s
elements. The returned {@code Set} has the same iteration order as
the source {@code Iterable}.

@param <T> the type of the returned {@code Set}'s elements.
@param iterable the source {@code Iterable}.

@return the {@code Set} created from the given {@code Iterable}.

@throws NullPointerException if {@code iterable} is {@code null}.
