Uncertainty propagation in C++

A set of drop-in classes that keep track of uncertainties along with calculations. Most math functions are reimplemented, allowing one to use these classes in place of the primitive arithmetic double type without extensive rewriting of code.

Word of warning

⚠️ Reported code coverage is optimistic. This library requires significantly more testing. ⚠️

Background
