A C++14-compatible physical units library with no dependencies and a single-file delivery option. Emphasis on safety, accessibility, performance, and developer experience.
From now on, anyone can just include "au/fwd.hh", and get
authoritatively correct forward declarations. These will be implicitly
tested automatically by adding an #include of this new file at the top
of every file that has a definition for which we now provide a forward
declaration: if we get a forward declaration wrong, we'll get a compiler
warning.
We also include fwd.hh in a few places where it lets us get rid of
some manual forward declarations.
The rep-named aliases move upstream into fwd.hh, because they'll be
directly useful for forward declaration use cases, and because you can't
"forward declare" an alias: you just have to move the definition
upstream.
Helps #232. To resolve it completely, we will need to provide a forward
declaration file for each individual unit file.
