A toolkit for handling data from IMU units when measuring movements during weight lifting.

Has primarily been tested with PyBerryIMU data.

This library includes bundled code from [x-io Technologies webpage] (http://www.x-io.co.uk/open-source-imu-and-ahrs-algorithms/), namely the C implementations of the Madgwick AHRS filter algorithm and the Mahony AHRS filter algorithm.

These have been modified slightly to make the C functions stateless and keep the states in the corresponding Python object wrappers instead.
