In microbenchmarks I tried, using `__builtin_expect` to indicate which branch was likely/unlikely was never faster, and often slower, than just omitting.

* Use CMAKE_CXX_STANDARD when available
If the use has provided the variable CMAKE_CXX_STANDARD use that instead of providing a default cache variable.
* Typo
* Azure pipeline (#8)

* nl @ eof
* trimming the pipeline and adding debug steps
* removing redundant lines
* change ctest to script cmd and remove debug
* removed bad char
* added dir change for ctest
* explicit output file and cmake standard
* test cat
* more ctest tests
* injecting failure in test for validation
* another test
* removing bad test
* massive matrix
* added parallel
* commenting everything but xcode out for testing purposes
* uncomment the other tests
* testing some variables
* rename
* changed macos versions
* adding one more layer of templates
* fixing jobs.yml
* idk what i'm doing
* slight modifications
* maybe some spaces will help
* removing 'variables.'

narrow() is now in gsl_narrow rather than gsl_util. Include gsl_narrow when exceptions are enabled. Ensures that #include <gsl/gsl> includes entire library as advertised in the documentation.
