/**
* Receives a string with specific caracters and replace them with date information based on the Date Object passed.
* @param formatStyle a string with or more of the caracters bellow (starting at line 15). <br />
* @param date the Date object with the date you want to format
*
* The folowing caracters are the ones to be replaced:
* <ul>
* <li><strong>d:</strong> Day of the month, 2 digits with leading zeros. Ex.: 01 to 31</li>
* <li><strong>D:</strong> A textual representation of a day, three letters. Ex.: Mon through Sun</li>
* <li><strong>j:</strong> Day of the month without leading zeros. Ex.: 1 to 31</li>
* <li><strong>l:</strong> A full textual representation of the day of the week. Ex.: Sunday through Saturday</li>
* <li><strong>w:</strong> Numeric representation of the day of the week. Ex.: 0 (for Sunday) through 6 (for Saturday)</li>
* <li><strong>z:</strong> The day of the year (starting from 0). Ex.: 0 through 365</li>
* <li><strong>F:</strong> A full textual representation of a month, such as January or March. Ex.: January through December</li>
* <li><strong>m:</strong> Numeric representation of a month, with leading zeros. Ex.: 01 through 12</li>
* <li><strong>M:</strong> A short textual representation of a month, three letters. Ex.: Jan through Dec</li>
* <li><strong>n:</strong> Numeric representation of a month, without leading zeros. Ex.: 1 through 12</li>
* <li><strong>t:</strong> Number of days in the given month. Ex.: 28 through 31</li>
* <li><strong>L:</strong> Whether it's a leap year. Ex.: 1 if it is a leap year, 0 otherwise.</li>
* <li><strong>Y:</strong> A full numeric representation of a year, 4 digits. Ex.: 1999 or 2003.</li>
* <li><strong>y:</strong> A two digit representation of a year. Ex.: 99 or 03.</li>
* <li><strong>a:</strong> Lowercase Ante meridiem and Post meridiem. Ex.: am or pm.</li>
* <li><strong>A:</strong> Uppercase Ante meridiem and Post meridiem. Ex.: AM or PM.</li>
* <li><strong>g:</strong> 12-hour format of an hour without leading zeros. Ex.: 1 through 12.</li>
* <li><strong>G:</strong> 24-hour format of an hour without leading zeros. Ex.: 0 through 23.</li>
* <li><strong>h:</strong> 12-hour format of an hour with leading zeros. Ex.: 01 through 12.</li>
* <li><strong>H:</strong> 24-hour format of an hour with leading zeros. Ex.: 00 through 23.</li>
* <li><strong>i:</strong> Minutes with leading zeros. Ex.: 00 to 59.</li>
* <li><strong>s:</strong> Seconds, with leading zeros. Ex.: 00 through 59.</li>
* <li><strong>u:</strong> Milliseconds. Ex.: 654.</li>
* <li><strong>U:</strong> Milliseconds since the Unix Epoch (January 1 1970 00:00:00 GMT). Ex.: 1309986224468.</li>
* </ul>
* @example
* <pre>
* var d:Date = new Date(2011, 7, 6, 14, 1, 58, 220);
* trace(DateUtil.formatDate("z - l - d/m/Y = h:i:s:u A", d)); // outputs: "186 - Wednesday - 06/07/2011 - 02:01:58:220 PM"

//How to use
var d:Date = new Date();//Now Date
//Outputs something like: 262 - Tuesday - 20/09/2011 - 02:58:05:236 PM
