        Formats a string replacing formatting specifiers with values provided as arguments
        which are formatted according to the specifier.
        This is an implementation of  python's % operator for strings and is similar to sprintf from C.
        Usage:
            resultString = formatString.format(value1, v2, ...);
        
        Each formatString can contain any number of formatting specifiers which are
        replaced with the formated values.
        
        specifier([...]-items are optional): 
            "%(key)[flag][sign][min][percision]typeOfValue"
            
            (key)  If specified the 1st argument is treated as an object/associative array and the formating values 
                     are retrieved from that object using the key.
                
            flag:
                0      Use 0s for padding.
                -      Left justify result, padding it with spaces.
                        Use spaces for padding.
            sign:
                +      Numeric values will contain a +|- infront of the number.
            min:
                l      The string will be padded with the padding character until it has a minimum length of l. 
            percision:
               .x     Where x is the percision for floating point numbers and the lenght for 0 padding for integers.
            typeOfValue:
                d    Signed integer decimal.  	 
                i     Signed integer decimal. 	 
                b    Unsigned binary.                       //This does not exist in python!
                o    Unsigned octal. 	
                u    Unsigned decimal. 	 
                x    Unsigned hexidecimal (lowercase). 	
                X   Unsigned hexidecimal (uppercase). 	
                e   Floating point exponential format (lowercase). 	 
                E   Floating point exponential format (uppercase). 	 
                f    Floating point decimal format. 	 
                F   Floating point decimal format. 	 
                c   Single character (accepts byte or single character string). 	 
                s   String (converts any object using object.toString()). 	
        
        Examples:
            "%02d".format(8) == "08"
            "%05.2f".format(1.234) == "01.23"
            "123 in binary is: %08b".format(123) == "123 in binary is: 01111011"
