…ate some corresponding test cases and documentation Allow option groups to use ignore_case ignore_underscore for inheritance Allow option groups to specify allow_extras even if the parent app doesn't in which case extra options flow down into the option_group.

…ome cleanup in the README.md Apply suggestions from code review Co-Authored-By: phlptp <top1@llnl.gov> allow callbacks for option_groups, and allow some other characters as flags

rework return values from _parse_* function to return true if the value was processed false otherwise, this simplified the logic and got rid of the pulling and clearing of the missing fields from option groups. add TriggerOff and TriggerOn helper functions and some tests for them add shapes example of multiple callbacks in order. allow specification of callbacks that get executed immediately on completion of parsing of subcommand add tests for enabled/disabled by default add _get_fallthrough_parent. To get the most appropriate parent to fallthrough to add enabled and disabled by default functions add positional_arity example Add a pre_parse_callback_ for apps. The Pre parse callback takes an argument for the number of remaining arguments left to process, and will execute prior to parsing for subcommands, and after the first option parse for option_groups.

* change the move function to _move_option and add an additional test add a validation check on min options to make sure it is even possible to succeed. add some additional tests to cover code paths and potential errors. add a number of additional tests and checks and fix some issues with the add function in option_groups clean up example and help formatting add option_groups example to play with move create_option_group to a member function using a dummy template add some optionGroup tests add min and max options calls and an associated Error call * add ranges example, add excludes to app for options and subcommands. * add some tests on ranges, and some subcommand tests with exclusion * add tests in optionGroups for some invalid inputs * add required option to subcommands and option_groups * add disabled flag * add disable option to subcommands and some more tests * start work on ReadMe modifications * update the readme with descriptions of function and methods added for option_groups * clear up gcc 4.7 warnings * some update to the Readme and a few more warnings fixed * Minor readme touchup
