- Update to version 0.4.2
  * Change the eps for geometry computations from 1e-4 to 1e-5 in 
    ``libroom``
  * Added a specialized ``is_inside`` routine for ``ShoeBox`` rooms
- Changes in 0.4.1
  * Issue #162 (crash with max_order>31 on windows), seems fixed by 
    the new C++ simulator
  * Added minimal `Dockerfile` example.
- Changes in 0.4.0
  * Improved Simulator with Ray Tracing
    - Ray Tracing in the libroom module. The function compute_rir() 
      of the Room object in python can now be executed using a pure 
      ray tracing approach or a hybrid (ISM + RT) approach. That's 
      why this function has now several default arguments to 
      run ray tracing (number of rays, scattering coefficient, 
      energy and time thresholds, microphone's radius).
    - Bandpass filterbank construction in ``pyroomacoustics.
      acoustics.bandpass_filterbank``
    - Acoustic properties of different materials in 
      ``pyroomacoustics.materials``
    - Scattering from the wall is handled via ray tracing method, 
      scattering coefficients are provided
      in ``pyroomacoustics.materials.Material`` objects
    - Function ``inverse_sabine`` allows to compute the 
      ``absorption`` and ``max_order`` to use with
      the image source model to achieve a given reverberation time
    - The method ``rt60_theory`` in ``pyroomacoustics.room.Room`` 
      allows to compute the theoretical
      RT60 of the room according to Eyring or Sabine formula
    - The method ``measure_rt60`` in ``pyroomacoustics.room.Room``
