+ * According to http://en.wikipedia.org/wiki/Bi-directional_text:
  * Bi-directional text is text containing text in both text directionalities,
  * both right-to-left (RTL) and left-to-right (LTR). It generally involves text
  * containing different types of alphabets, but may also refer to boustrophedon,
  * which is changing text directionality in each row.
  *
  * Utility class for formatting display text in a potentially
  * opposite-directionality context without garbling layout issues.
  * Mostly a very "slimmed-down" and dart-ified port of the Closure Birectional
  * formatting libary. If there is a utility in the Closure library (or ICU, or
  * elsewhere) that you would like this formatter to make available, please

  * attacks and other nasty business. This of course is always true, but the
  * escaping cannot be done after the string has already been wrapped in
  * mark-up, so the BiDi formatter also serves as a last chance and includes
  * escaping services.
  *
  * Thus, in a single call, the formatter will escape the input string as
  * specified, determine its directionality, and wrap it as necessary. It is
  * then up to the caller to insert the return value in the output.
