Problem
We have a comprehensive README but would like new users to get a quick idea of what Commander does, whether they like the look of it, and how to start writing code.
Related: #1588
Solution
Write a brief overview of Commander supported by new single-command and multiple command examples.
The single-command example deliberately leaves out the option descriptions to show a minimal program with just the two main option types declared. The example usage shows Commander being strict, with a suggestion as a bonus!
The second example shows features common to a more complete program without going into details: help descriptions, name, version, subcommand, command-argument, default value for an option. The example usage shows the help output which is an important feature.
