Feature Request: LabelledArrays in tutorials

[metanoid]

For larger problems, something like LabelledArrays.jl would be very convenient.

Currently the docs don't mention LabelledArrays, I think it would be a good addition to have a few of the tutorials showing both the current version and the same problem solved with LabelledArrays as a DSL.

I agree. We should probably integrate ModelingToolkit and LabelledArrays into the tutorials.
