Sort iteration according to human logic

[daniel-sol]

Iteration names are now sorted according to machine logic.
E.g :

pred-1, pred-100, pred-2, pred-3

For a human it is desirable with logic:
pred-1, pred-2, pred-3, pred-100

[perolavsvendsen]

There is no standard on iteration (ensemble) names. It is a mix of conventions and free text. (E.g. does the pattern described above (pred-1, pred-2, etc) exist outside Troll?)

It is difficult to find a universal rule that will work.

Example: iter-0, iter-2, iter-10, pred.
Example: iter-0, iter-2, pred-1, pred-2, pred-10.
Example: myiter, myotheriter, final, first, test

Trying to sort on name I think could quickly explode into quite a lot of code. Perhaps better to sort on datetime? First created, first listed?
