* add expanded type_size specification * add some more checks for type_size_max * continued work on getting type sizes more flexible * make some more tweaks to option to split up validate and reduce sections * git rid of exceptions on the type_size functions exceptions, allow any number to be entered for the min and max and don't make a distinction between flags and other types. * add expected count * add the allow extra args flag in an option * start working in allow_extra_args * write some stuff in the book, and continue working on the failing test cases * fix a few more of the helpers tests * a few more test cases running * all tests pass, fixing calls in ini files * get vector<pair> working and all tests passing * change callback to use reference to remove allocation and copy operation * add support and test for vector<vector<X>> * change Validators_ to validators_ for consistency * fix linux warnings and errors by reording some templates and adding some typename keywords * add support for std::vector<X> as the cross conversion type so optional<std::vector<X>> is supported using the full template of add_option. * a few more test cases to take care of some coverage gaps * add missing parenthesis * add some more tests for coverage gaps * add test for flag like option * add transform test for `as<X>` function and make it pass through the defaults * add a few more tests and have vector default string interpreted correctly. * add test for defaulted integer, and route default string for defaulted value which would otherwise be empty * some code cleanup and comments and few more test coverage gap tests * add more tests and fix a few bugs on the type size and different code paths * remove path in results by fixing the clear of options so they go back to parsing state. * get coverage back to 100% * clang_tidy, and codacy fixes * reorder the lexical_conversion definitions * update some formatting * update whitespace on book chapter
