* Update options.md book chapter and the readme to better reflect current usage and the modifications to the add_options templates. add support in add_option for wrapper types, such as std::optional, boost::optional or other types with a value_type trait. Add support for generalized containers beyond vector, add support for nested tuples and vectors, and complex numbers directly in add_option. This includes several new type traits and object categories. Upgrade the google test version to better support templated tests. add support for vector argument separator `%%` * update formatting to match recent changes * Apply suggestions from code review Co-authored-by: Henry Schreiner <HenrySchreinerIII@gmail.com>
