/*
 * This module provides common functions used by many applications
 * most of them are addons to existing objects
 *
 * 1) window-object:
 *      * parseCurrency( value, symbol_name, type )
 *          similar to parseFloat parsing a currencyFormatedString and return the float-value
 *      * parseFromFormatedNumber( number, decimal_sep, thousand_sep, suffix, prefix )
 *          similar to parseFloat parsing a formatedString and return the float-value
 *      * parseFloatComma( val )
 *          parses a number string like parseFloat does but uses the , as digit-seperator
 * 2) document-object:
 *      * getElementById(id)
 *          adds getElementById for versions of IE using document.all
 * 3) Number-object:
 *      * toFixed( decimal_digits )
 *          Browsers like NN >= 6.x and IE >= 5.x provid this function built in. Others
 *          like IE 4.x and e.g. Konqueror for these browsers we implement them
 *      * toCurrencyFormatedString(decimal_digits, symbol_name, type)
 *          Does some nice formating on numbers like you're already familiar when using e.g. Excel
 *      * formatNumber( decimal_digits, decimal_sep, thousand_sep, suffix, prefix )
 *          Formats a number like want it
 * 4) Date-object:
 *      * getDateOutOfString( val ) => static
 *          returns a date out of a string
 *      * makeStringOutOfDate()
 *          returns the Date as a. At the moment e.g. 01.01.2002
