Ensure that the order how list of trails comes when call trails:store/1 be the same when call trails:all/0.

[cabol]

Currently, when trails:store/1 is invoked, list of trails/routes are stored into an ETS table (in a set structure), so it breaks the order how routes comes in the list, and due to this trails:all/0 returns the list in different order.

One option could be use an ordered_set structure for ETS table, BUT will be necessary add an additional argument (for example a consecutive integer) in order that the tree can be sorted in the right way.
