Non dimensionalisation of systems

This would be a very good feature to have in future with MTK

Unitful has recipes for Buckingham pi groups, which may prove useful

Wow, that's pretty interesting. I'm working on expanding the capability of the unit-handling (#1252 / #1250). This would be a great follow-on project.

@lamorton Came across another resource for non-dimensionalisation algorithm for ODEs(i am not currently competent to implement it though ).
Polynomial Time Nondimensionalisation of Ordinary Differential Equations via their Lie Point Symmetries

I believe that a more complete version (as mentioned on ResearchGate) is https://hal.inria.fr/hal-00668882v2/document
One of the authors gave an invited talk on the algorithm recently at the Maple conference, one can register (for free) and watch the recording.
