- 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`` 
      allows to measure the RT60 of the simulated RIRs
  * Changes in the Room Class
    - Deep refactor of Room class. The constructor arguments have 
      changed
    - No more ``sigma2_awgn``, noise is now handled in 
      ``pyroomacoustics.Room.simulate`` method
    - The way absorption is handled has changed. The scalar 
      variables ``absorption`` are deprecated in favor of 
      ``pyroomacoustics.materials.Material``
    - Complete refactor of libroom, the compiled extension module 
      responsible for the room simulation, into C++. The bindings 
      to python are now done using pybind11.
    - Removes the pure Python room simulator as it was really slow
    - ``pyroomacoustics.transform.analysis``, ``pyroomacoustics.
      transform.synthesis``, ``pyroomacoustics.transform.
      compute_synthesis_window``, have been deprecated in favor of
      ``pyroomacoustics.transform.stft.analysis``, 
      ``pyroomacoustics.transform.stft.synthesis``,
      ``pyroomacoustics.transform.stft.compute_synthesis_window``.
    - ``pyroomacoustics.Room`` has a new method ``add`` that can be 
      used to add either a ``SoundSource``, or a 
      ``MicrophoneArray`` object.  Subsequent calls to the method 
      will always add source/microphones. There exists also methods
      ``add_source`` and ``add_microphone`` that can be used to add
      source/microphone via coordinates. The method 
      `add_microphone_array`` can be used to add a 
      ``MicrophoneArray`` object, or a 2D array containing the
      locations of several microphones in its columns.  While the
      ``add_microphone_array`` method used to replace the existing 
      array by the argument, the new behavior is to add in addition 
      to other microphones already present.
  * From Issue #150, increase max iterations to check if point is 
    inside room
  * Fixed normalization part in FastMNMF
  * Added `room_isinside_max_iter` in `parameters.py`
  * Default set to 20 rather than 5 as it was in `pyroomacoustics.
    room.Room.isinside`
  * Changed while loop to iterate up to `room_isinside_max_iter` in 
    `pyroomacoustics.room.Room.isinside`
  * Changed initialization of FastMNMF to accelerate convergence
  * Fixed bug in doa/tops (float -> integer division)
  * Added vectorised functions in MUSIC 
  * Use the vectorised functions in _process of MUSIC
- Skip python36 build, because NumPy in TW dropped it (NEP 29)
- Use system eigen3 headers
- Clean test rig setup
  * Only test on x86_64: All other platforms fail because of
    rounding errors vs. too tight precision requirements in tests.
