Updates to the readme
update the readme with some documentation
add a few more tests to complete code coverage
update with count strings in flags instead an array of strings for each count
add the '!' shortcut notation. add some checks on the help output
allow the false flag syntax to support --option{false}
add a bool lexical cast to make everything consistent when converting to a bool. Moved a few functions around
make the command line behave like the INI file wrt flags, flag options are allowed to process the value so `--flag=false` actually does the expected thing.
Add functionality similar to click style argument that allow specifying a false flag that when used generates a false result on the flag.
increment the parse_ variable on unnamed subcommands.
update the readme, and add a formatter test for nameless subcommands in nondefault group with other named subcommands.
add a test of default arguments
add a formatter test
add tests for unnamed subcommands and an example of the partitioned subcommands.
change the app_p to be a shared_ptr so you can add an App later on and merge them together
add the ability to add unnamed subcommands that allow partitioning on options into multiple apps.
in progress: formatters
