 * 
 * Notes & Thanks
 * 
 * many thanks to advweb.nanasi.jp for his bug fixes
 * jsHashtable is now used also, so thanks to the author for that excellent little class.
 *
 * This plugin can be used to format numbers as text and parse text as Numbers
 * Because we live in an international world, we cannot assume that everyone
 * uses "," to divide thousands, and "." as a decimal point.
 *
 * As of 1.2 the way this plugin works has changed slightly, parsing text to a number
 * has 1 set of functions, formatting a number to text has it's own. Before things
 * were a little confusing, so I wanted to separate the 2 out more.
 *
 *
 * jQuery extension functions:
 *
 * formatNumber(options, writeBack, giveReturnValue) - Reads the value from the subject, parses to
 * a Javascript Number object, then formats back to text using the passed options and write back to
 * the subject.
 * 
 * parseNumber(options) - Parses the value in the subject to a Number object using the passed options
 * to decipher the actual number from the text, then writes the value as text back to the subject.
 * 
 * 
 * Generic functions:
 * 
 * formatNumber(numberString, options) - Takes a plain number as a string (e.g. '1002.0123') and returns
 * a string of the given format options.
 * 
 * parseNumber(numberString, options) - Takes a number as text that is formatted the same as the given
 * options then and returns it as a plain Number object.
 * 
 * To achieve the old way of combining parsing and formatting to keep say a input field always formatted
 * to a given format after it has lost focus you'd simply use a combination of the functions.
 * 
 * e.g.
 * $("#salary").blur(function(){
 * 		$(this).parseNumber({format:"#,###.00", locale:"us"});
 * 		$(this).formatNumber({format:"#,###.00", locale:"us"});
 * });
 *
 * The syntax for the formatting is:
 * 0 = Digit
 * # = Digit, zero shows as absent
 * . = Decimal separator
 * - = Negative sign
 * , = Grouping Separator
 * % = Percent (multiplies the number by 100)
 * 
 * For example, a format of "#,###.00" and text of 4500.20 will
 * display as "4.500,20" with a locale of "de", and "4,500.20" with a locale of "us"
 *
 *
 * As of now, the only acceptable locales are 
 * Arab Emirates -> "ae"
 * Australia -> "au"
 * Austria -> "at"
 * Brazil -> "br"
 * Canada -> "ca"
 * China -> "cn"
 * Czech -> "cz"
 * Denmark -> "dk"
 * Egypt -> "eg"
 * Finland -> "fi"
 * France  -> "fr"
 * Germany -> "de"
 * Greece -> "gr"
 * Great Britain -> "gb"
 * Hong Kong -> "hk"
 * India -> "in"
 * Israel -> "il"
 * Japan -> "jp"
 * Russia -> "ru"
 * South Korea -> "kr"
 * Spain -> "es"
 * Sweden -> "se"
 * Switzerland -> "ch"
 * Taiwan -> "tw"
 * Thailand -> "th"
 * United States -> "us"
 * Vietnam -> "vn"
