	Test?code?for?the?BMP085?Barometric?Pressure?Sensor.
	We‘ll?first?read?all?the?calibration?values?from?the?sensor.
	Then?the?pressure?and?temperature?readings?will?be?read?and?calculated.
	Also?attempts?to?calculate?altitude?（remove?comments）
	The?sensor?is?run?in?ultra?low?power?mode.
	Tested?on?a?3.3V?8MHz?Arduino?Pro
	A4?（PC4）?->?SDA
	A5?（PC5）?->?SCL
	No?Connection?to?EOC?or?XCLR?pins
