Measurements data sent from server contains separate and unsorted measurements from accelerometer and gyroscope.
Also, accelerometer and gyroscope data have different timestamps associated to readings from sensors. (Approx time between measurements is ~80ms for accelerometer and ~40 for gyroscope) Both of these were sorted, resampled to 10ms, interpolated and merged together in the format of [timestampUtc,acc_x,acc_y,acc_z,gyro_x,gyro_y,gyro_z,measurementId,activity,repetitions]

Resampling to 10ms is motivated by experiments on the data in analyze.ipynb, but this value and method is open for further investigation.
