New version uses functions not macros. The use of template functions allows for enforcement of type-safety, which is implemented using static_assert. The old implementation is preserved for posterity. A header guard was added. I found the old macro names confusing, so I used new names, but I map the old names in the source onto them so the application source does not change.

Some of us think C++ standard parallelism is going to be important in HPC.
This is very easy to implement in QS. The performance looks comparable to OpenMP, although I only tested Clang 12 on an Ampere Altra Q80.
The GPU version of this will come later. There are some nuances there that I haven't resolved.
This PR includes #43.
