Manages identifiers of any type.  This represents the default way {@link TinkerGraph} has always worked.
In other words, there is no identifier conversion so if the identifier of a vertex is a {@code Long}, then
trying to request it with an {@code Integer} will have no effect. Also, like the original
{@link TinkerGraph}, it will generate {@link Long} values for identifiers.
