AG1LE Mauri d8959c15cb 2014-JAN-19 
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.

AG1LE Mauri ab2a727620 Changed program name to bmorse (b stands for bayesian). 
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
 2013-12-29 23:59:42 -05:00
AG1LE Mauri 995b9b17dc Added more command line options. 
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
