Instantiate inside a command object's methods (usually interact and execute but not limited to)

   $io->title("My Title");

2. Sections: Creates a section header with a single bar underline
   $io->section("My Section");

3. Content Output:
   Creates a text block
   $io->text("Your message here");
   Creates a bulleted list
   $io->listing(["item1","item2","item3"]);
   Creates a table
   $io->table(["header1","header2","header3"],[ ["A","B","C"], ["D","E","F"], ["G","H","I"] ]);
   Prints a new line
   $io->newLine();

4. Admonition Methods: success, warning, caution, note, comment
   Print out a padded and colored message
   $io->success("You Win!");
$io->error("You Fail!");

5. Progress Bar
   Creates an interactive progress bar
   $io->progressStart(100);
$io->progressAdvance(10);
$io->progressFinish();

6. Questions
   $io->ask("What is your name?");
$io->confirm("Are you sure?");
$io->choice("What is your favorite color?",["red,"blue","yellow"]);

7. Questions for missing arguments and options
   $io->askForMissingArgument( $argument, $question, $default = null, $validator = null, $maxAttempts = null, $comment = null, $commentFormat = "Argument [%s] set to: %s" )
$io->askForMissingOption( $option, $question, $default = null, $validator = null, $maxAttempts = null, $comment = null, $commentFormat = "Option [%s] set to: %s" )
