Data structure composability

[cashaffer]

A use case for this feature is Figure 7.17 on Page 247 of http://people.cs.vt.edu/~shaffer/Book/JAVA3e20120605.pdf

I would like a way (in this example) to define a JSAV array where the elements of the array are JSAV linked lists, and each array position contains a pointer to its linked list.

Comment from Ville:

I'm not sure what you describe above as an example is a feature of the linked
list or array or JSAV in general. The way the kind of setup you describe can be
achieved once issue #68 is implemented is to have an array, graphical primitive
lines positioned relative to array indices, and linked lists positioned
relative to the array index/lines.

I would prefer if there were a simpler mechanism than the AV developer doing this by hand as described here. I don't want to have to explicitly lay out the link from the array cell to the linked list and position each linked list. I just want to define the relationships in a fairly intuitive way (by declaring the elements of the array to be JSAV objects), and then have the layout handled for me.
