Add:

	- create a unsetBit(bitNumber) method to delete a value of a bit inside the object
	
	- create a ISO8583Util Class that give some util method like:
		- intToBCD
		- BCDToInt
		- getTimeGMT (to bit 12)
		- GetDateType (to bit 13)

Fix:

	- ...

Think about:

	- Improve ... improve ... improve 
	
	- Add support to "BCD" sizes in LL LLL types.
		ASCII LL size and ASCII value inside '123456' ->  '06123456'
		BCD LL size and  ASCII value inside '123456' -> '\x06' + '123456'
		ASCII LLL size and ASCII value inside '123456' ->  '006123456'
		BCD LLL size and  ASCII value inside '123456' -> '\x00\x06' + '123456'
		
	- Improve support to "binary" data
		i.setBit(3,'\x00\x01\x02')
		
	- Make sense setBit(1,'xxx') ?	
		Maybe the dialet need to have the 2 bitmap inside with no value because it's automatic that 2 be present when bit large than 64 is inside... 
		But .. Today work :) by the way ... xxx is ignored...
		
	- It's important separate the size and the value of LL and LLL types?
		Example, bit 2 is LL:
			Today -> i.setBit(2,'123') -> i.getBit(2) -> 03123
			Think -> i.setBit(2,'123') -> i.getBit(2) -> 123
		It was build in this way because the size can be important in some cases, but we can determine the size len(i.getBit(2)) ...
		If the partner send a ISO8583 with wrong size?
		
	- Make a XML builder that convert a ISO8583 to a XML object and a XML to ISO8583...
		<ISO8583>
			<mti>0200</mti>
			<bitmap>600000000000000</bitmap>
			<bits>
				<bit>
					<number>2</number>
					<value>03123</value>
					<type>LL</type>
				</bit>
				<bit>
					<number>3</number>
					<value>300000</value>
					<type>N</type>
				</bit>
			</bits>
		</ISO8583>
		
	- Use log4Python to improve debug information
	
	- Support Python V3
	
	- Improve errors:
		- validate values
		
	- Improve the package name / structure
		- today: FROM ISO8583.ISO8583 import ISO8583
		- future: FROM iso8583 import ISO8583 
		
	- Create more examples

	- Create benchmarks with JPOS
	
	- Support EBCDIC ...
