   * This class allows the formatting of dates by using format string. |

   * Format strings are: |

   * | 
						|
   *  - %A => long_weekday_format - Full name Ex: Tuesday | 
						|
   *  - %a => short_weekday_format - Three letter abbreviation Ex: Tue | 
						|
   *  - %B => long_month_format - Full name Ex: October | 
						|
   *  - %b => short_month_format - Three letter abbreviation Ex: Oct | 
						|
   *  - %x => standard_format_specifier - defined by the locale | 
						|
   *  - %Y-%b-%d => default_date_format - YYYY-Mon-dd | 
						|
   * | 
						|
   * Default month format == %b | 
						|
   * Default weekday format == %a |
