col: high-level console color formatting for Ruby

If you want a dash of color in your Ruby console program, use Term::ANSIColor.
If your color formatting requirements are more complicated, use Col.
Col provides as much convenience as possible without modifying builtin classes.

=== SYNOPSIS

    require 'col'

    puts Col("Hello world!").red.bold

    puts Col.inline(
      "Hello ",   [:red, :bold, :on_white],
      "world!",   :b_oy
    )
