Console is a helper class for displaying super-ASCII strings on the console.

Console is needed when you want to mix multi-column (e.g. Chinese, Japanese and
Korean characters) and single-column (e.g. ASCII) characters and know how much
horizontal realestate the result takes on the screen. This is generally
necessary when you want to have internationalization support in a console
program.

The Console gem currently provides these methods:

- Console.display_width: calculates the display width of a string
- Console.display_slice: returns a substring according to display offset
  and display width parameters.

If you require 'console', you will get just those methods.

If you require 'console/string', you will get String#display_width and
String#display_slice methods directly on all strings.
