Unitful Values

[eloiseyang]

Is your feature request related to a problem? Please describe.
Attaching units to physical values is a common feature of scientific codes. Our current solution in many of our matlab codes is to apply the unit transformation factors as needed (e.g. x = x * 1000 to convert from kilograms to grams).

Describe the solution you'd like
This is a complicated software task, so I'm not sure this is something we want to create ourselves. We should investigate libraries that already implement unitful values and think about whether or not we want to use them.

Describe alternatives you've considered
The current solution is not bad, but I think this could be nice. I also think it could over complicate our code. I'd like to open a discussion about it.

Here's a package that could suit our needs, for example.
