good checkpoint for adding package creation including jiffy itself
Fixed a major bug where i was iterating over a list, and delete as i went.  But
this changes the existing index, reducing the length by one after each delete.

it leads to skipping elements that need to be searched.

for ordr in group_order[:]:
    group_order.remove(ordr)

replaced

for ordr in group_order:
    group_order.remove(ordr)

also, in general, delete with remove referencing value rather than then del group_order[index]
