Small update with (mostly) formatting changes.

• cleaned up leftover nonstandard ssize_t
• changed formatting for logn in big-O complexity formulas
• added missing parenthesis

Content complete release

This release is this book's first content-complete release (for C++20).

While this doesn't mean that this is the last update (there will be a C++23 update once there is sufficient compiler support), I need to concentrate on other bigger projects. This book was constantly looming over my head as unfinished.

There are too many small changes to summarize here, but the big one is that each example in the book now has a Compiler Explorer link.

Enjoy 😁

Formatting cleanup & new chapter

This release has two main updates:

• information about ADL was moved (and expanded) to a separate chapter from std::swap
• formatting cleanup: line breaks in places and code blocks now break across pages

Fixed page numbering, VSCode+Devcontainer configuration

• fixed missing page numbers
• added configuration for VSCode and devcontainer (see readme.md)
• small text changes

Release with C++20 views

• added a chapter about C++20 range support with a section covering each of the views
• updated cover page

Added index and cover page.

This is a small update adding an index and a cover page.

First pre-release

The main chapter is done content-wise. Ready for early reviews.
