All versions

Another desire has been to deliver all version of a given object.
This is not on the mission statement for Overpass API:
First, it does not make much sense because the geometry of a way or relation can change
without a new version.
Second, Overpass API is designed around time slices and not object's life cycles.
Nonetheless, I have implemented a pair of functions that allows at least the baseline functionality:

timeline(way,100);
for (t["created"])
{
retro (_.val)
{
way(100);
out meta;
}
}
