Free C++ unit of measurement (UoM) library (permissive software license).

Features:

• Header only with no dependencies on external libraries.
• "std::ratio on steroids" implementation: effectively no limit on unit multiple supporting all SI unit prefixes.

NOTE: This new project is, as of September 2023, still a work-in-progress so DO NOT USE until v1.0 has been released with a full suite of unit tests.
