Added support for side airbags, calibration of the accelerometer, smoothing the input to eliminate false values. THIS HAS NOT BEEN TESTED. I DO NOT KNOW IF IT WILL RUN OR NOT. I AM NOT LIABLE FOR ANY DAMAGE, BROKEN FAMILIES, OR DEATHS IF YOU USE ANY OF MY CODE. THIS IS AN ALPHA PRE-RELEASE. NOT TESTED!!!!!!!!!!!!!!!!1
