TODO

• express marker position in space as quaternion
  • will be possible to measure arm position from any place
  • will be possible to estimate how confident is the readout
• add mapping: (angle, stiffness) -> (confidence)
• build neural network
  • use Levenberg-Marquardt backpropagation with single hidden layer
• use histograms to estimate how good is the readout
• use logger instead of printing
