Add a Command.contains_sequence() method that tests argument string + position in order to support command suite style applications.

e.g.,

For the command:

$ tester [subcmd] [subsubcmd] [..args]

provide a test that allows library user to do the following:

let c = Command::new();

if c.contains_sequence(vec![“filter”, “help”]) {
    // received help request for filter subcommand
}

Command::is_version() method as a concise test for -v or --version options.

This converts to correct terms for the Unicode code points that are used for the idiom

Support automated testing for --usage switch with Command::is_usage() method

This appears to be a Travis CI Rust installation problem. Reported here: https://travis-ci.community/t/macos-rust-beta-build-failures/803 and await response.

Command::contains_all_options() method

Add support for automation of a check that confirm that the user included only options that are supported in the application.

Command::contains_one_option()

In the vein of getopt's optind. Will represent the index of the last parsed option in the command sequence to permit identification of subsequent arguments for additional parsing by the library/library user.

std::path::Path from String

POSIX defined options with single hyphen and multiple characters where each character represents a different option switch

e.g.:

-abc where option indicates -a -b -c

Command::is_help() as concise test for -h or --help options

Grammar struct used to define application syntax. Data in grammar used for validations. Definition of Grammar is optional and only used when CLI application author wants to use commandlines library for validation of user command entry.
