      // - Lay out each keyboard in rows of sub-arrays.  Each sub-array
      //   represents one key.
      // 
      // - Each sub-array consists of four slots described as follows:
      //     example: ["a", "A", "\u00e1", "\u00c1"]
      //
      //          a) Normal character
      //          A) Character + Shift or Caps
      //     \u00e1) Character + Alt or AltGr
      //     \u00c1) Character + Shift or Caps + Alt or AltGr
      //
      //   You may include sub-arrays which are fewer than four slots.  In
      //   these cases, the missing slots will be blanked when the
      //   corresponding modifier key (Shift or AltGr) is pressed.
      //
      // - If the second slot of a sub-array matches one of the following
      //   strings:
      //       "Tab", "Caps", "Shift", "Enter", "Bksp", "Alt" OR "AltGr"
      //   then the function of the key will be the following,
      //   respectively:
      //     - Insert a tab
      //     - Toggle Caps Lock (technically a Shift Lock)
      //     - Next entered character will be the shifted character
      //     - Insert a newline (textarea), or close the keyboard
      //     - Delete the previous character
      //     - Next entered character will be the alternate character
      //
      //   The first slot of this sub-array will be the text to display on
      //   the corresponding key.  This allows for easy localisation of key
      //   names.
      //
      // - Layout dead keys (diacritic + letter) should be added as arrays
      //   of two item arrays with hash keys equal to the diacritic.  See
      //   the "this.VKI_deadkey" object below the layout definitions. In
      //   each two item child array, the second item is what the diacritic
      //   would change the first item to.
      //
      // - To disable dead keys for a layout, simply assign true to the
      //   this.VKI_layoutDDK (DDK = disable dead keys) object of the same
      //   name as the layout.  See the Numpad layout below for an example.
      //
      // - Note that any characters beyond the normal ASCII set should be
      //   entered in escaped Unicode format.  (eg \u00a3 = Pound symbol)
      //   You can find Unicode values for characters here:
      //     http://unicode.org/charts/
      //
      // - To remove a keyboard, just delete it, or comment it out of the
      //   source code
