* Use '<thing> template' i.s.o. 'template <thing>'

The word 'template' is often wrongly used as an adjective to the 'thing'
it becomes when instantiated.

The rules NL.11 (Make literals readable) and NL.15 (Use spaces
sparingly) are placed in inverted order in the text flow, swap them.

"Make your code thread-safe" usually means "don't use global state."
Advice to replace global state with `thread_local` state is usually misguided.

* Adjust the spacing for consistency

* Adjust the spacing for consistency-2

The _bad_ example wasn't annotated as such and a perfectly fine function
name was marked bad.

Annotate the example as bad and remove the misleading function name
annotation.

For some reason the trailing `e = 3` seemed more of a red flag

is trying to make some constants for hexadecimal translation.

* dumb -> inefficient

* Actually detect negative sizes by following ES.106

And don't use senseless one letter names

Changed the two anchors back (anchors need to stay stable and don't
display visibly anyway)
Switched "non-public" back to hyphernated (to use hyphenation
consistently)

* Add hyphens to words that begins with a non

* Remove hyphens in nonpublic

Added example to CP.61: Use an async() to spawn a concurrent task

* Casting away const isn't undefined behavior, but modifying a constant is

You can cast away `const` as much as you like, as long as you never write to variable.

* rewording for clarification

thus I propose removing R.6 and moving some of its contents into I.2.

* Added two commonly used coding guideline documents

* Update CppCoreGuidelines.md

To adjust example comment and Enforcement per PR #1551 comments
