I think we should use OrderedSets from https://github.com/JuliaCollections/OrderedCollections.jl for, at least, the cellsets in the grid. This will ensure that we have both fast lookup and that we can iterate cells in order. This will require JuliaCollections/OrderedCollections.jl#100 and a new release of that package so that we can sort! in the Grid constructor and in addcellset.

Should I address this already in the linked PR or leave it as a good first issue?

This could probably be pretty self-contained PR (easier to review). Opened this mostly to see if people liked the idea :)

What's the drawback between ordered sets and normal sets? :)

What's the drawback between ordered sets and normal sets? :)

If the problem is big and you iterate over the set, i.e. unordered, you need to visit very different chunks of data for e.g. internal variables

The bigger issue is that "normal" sets are unordered and ordering may even mutate. E.g. you cannot easily iterate over the entries in ascending order.

Replace Set with OrderedSets in grid collections
bee3d7b 
This patch changes the use of `Set` to `OrderedSet` in the grid. This
means that e.g. loops over these sets follow the original specified
order. This is important for performance since it can reduce
cache-misses, for example. Fixes #631.
