Release notes:

• LongwaveModePropagator.defaultmesh now has different default behavior for transmitter frequencies below 12 kHz.
  • The previous default used the internal trianglemesh function and searched for eigenangles in the region of the lower right complex quadrant near the positive real and negative imaginary axes. At low frequencies the eigenangles can have large real and large negative imaginary components, which were not contained in the trianglemesh. Now RootsAndPoles.rectanglemesh is used for these lower frequencies.
  • Fixed #68
