The LPF is now defined in terms of the time constant instead of alpha. A
two-dimensional vector view has been added that allows the user to view
the acceleration on the X and Y axis as a vector with a magnitude and
direction. The tilt gauge has been updated so it draws in a much cleaner
way. The main plot layout has been optimized for tablets. The user now
has the ability to select the frequency of the acceleration sensor.
