4589	Investigate using AvlSetInt for Adjacency Matrix	Martin Sjölund	Lennart Ochel	Currently, our adjacency matrixes use a `list<list<Integer>>` structure, but the order of these integers does not matter. If we start using `list<AvlSetInt.Tree>`, we could do operations like join and intersect without expensive operations. We would also not need to use `List.unique`. For the `comSubExp` module, the use of a single line of an intersection call used more than 50% of the total used memory of the entire translation process.	enhancement	new	high	Future	Backend				Lennart Ochel Willi Braun
