BMP180 code

Here is the code for running the BMP180 pressure sensor:

>>> import Adafruit_BMP.BMP085 as BMP085
>>> sensor = BMP085.BMP085()
>>> sensor.read_temperature()
24.3
>>> sensor.read_pressure()
102543L
>>> print 'Pressure = {0:0.2f} Pa'.format(sensor.read_pressure())
Pressure = 102543.00 Pa
>>> sensor.read_altitude()
-99.8422490470797
>>> sensor.read_sealevel_pressure()
102542.0
