Added morse class in bmorse.h
Moved common structs into class variables so that I can instantiate multiple morse decoders, for each CW frequency in Morse Audio file
Removed unnecessary static variables.
Cleaned up all files and changed morse.h tp bmorse.h
2013-DEC-29
Added more options to enable debugging and testing bmorse decoder while using WAV audio files as source.
Bit filter (-bfv) option does envelope smoothing - 10 msec rise time assumption based on experiences with FLDIGI.
Plot option (-plt) enables piping such as "bmorse -plt <sndfile> | xplot" to visualize the CW envelope.
AGC option (-agc) has fast rise and slow decay in case original signal has very large dynamic range.
AMP option (-amp) allows to multiply envelope signal with a constant.
DUR option (-dur) allows manually to set Bayesian decoder sample duration (used in path.c).
FFT option (-fft) enables either FFT based signal recovery or just low pass filtering.
- FFT has also peak_detection() to find if there are multiple signals in the audio frequency range.
- Parameter "delta" sets peak detection threshold
- Width (-wid) and length (-len) parameters can be used to set FFT size and chunking
Added back ability to decode from text file that contains real valued samples (one per line assume 4 Khz sample rate).
Cleaned up shared structures into morse.h
