New functionality includes:
- run-time selectable noise models: point|surface
- run-time selectable window models: Hanning (+ options symmetric, extended), uniform
- calculates PSD (Pa^2/Hz) and dB/HZ; SPL (Pa^2) and dB
- calculates 1/3 octave data, with centre frequency 1kHz
surfaceNoise only:
- reads ascii/binary ensight surface data (requires collateTimes option)
- generates graphs for surface average quantities
- operates in parallel
