Title: Filters + New Function getEstAltitude() + New Board (GY-88)

+ Added a running average filter for heading (and made it like a compass)
+ Added getEstAltitude() which uses a complementary filter of the
barometer and accelerometer
+ Added a 1D Kalman Filter for the barometer pressure readings.

*all code is from the experimental processing sketch.*
