Change Log:
1.) Removed ifwt.c from project. Was never really part of it anyway. 
2.) Replaced pipein.c with get_data.c which is much more flexible and  
    allows for arbitrary M by N ascii data files to be imported. Note
    that currently only 1, 2, or 3 column input is supported. 
3.) Speaking of that, 1, 2, or 3 column input is now supported. See
    below in the DESCRIPTION section for more information.
4.) Added a gaussian routine for bootstraping (Box-Muller).
5.) Added a poisson routine for bootstraping (Used Knuth's algorithm from
    The Art of Computer Programming, Vol2).
6.) Added wavlet_variance and heatmap routines to the project.

NAME
         fwt - decomposes an array of numbers into wavelet coefficients.

 
 SYNOPSIS
         fwt [OPTION]... < [file]...
  DESCRIPTION
         This software expects input in the form of ascii numbers with one, 
	 two, or three columns. If one column then that column must be the 
	 series to to transform. If two columns then the first column is 
	 the index (such as time) and the second is the series (signal) to 
	 be transformed. If three columns are supplied then the first 
	 column is the index, the second is the series (signal) to be 
	 transformed, and the third column is the uncertainty. If only one 
	 or two columns are given then the uncertainty is assumed to be 
	 the square root of the signal. columns must be of length 2^m where 
	 m is a positive integer. The maximum size of m depends on the 
	 machine running the code. It is the user's responsibility to 
	 guarantee the length of the data. In any case the signal is assumed 
	 to be uniformly sampled.

  
         Input is supplied in the form of pipes or redirection. This can be 
	 accomplished via:
           cat INPUTFILE | fwt
         or 
           fwt < INPUTFILE
 
         Different wavelet filters can be chosen via command line options.
 
           cat INPUTFILE | fwt -d2
         or
           cat INPUTFILE | fwt -c12 --offset 3
 
         If no wavelet filter is specified the default, -d2 (aka the Haar 
	 basis), is assumed.
  
         A positive offset to the signal may be specified by the --offset 
	 option or -o For example, if there were an array 1,2,3...7,8 and 
	 an offset of one were given then the signal would be processed as 
         8,1,2...6,7. This is useful when adjusting the appearance of a 
	 scalogram. Any statistical measure which sums over position
         values in an octave will be insensitive to offset.
 
 
         The output of the code is also two column ascii data. The first column 
	 is index information and the second column holds the transformed signal. 
 
 OPTIONS
         -d NUM, --daub=NUM Daubechies family of wavelet filters. NUM=2 gives 
	               the Haar filter. NUM determines wavelet support and can be 2, 4, 6.
 
         -c NUM, --coif=NUM Coiflet family of wavelet filters. NUM determines 
	    	       wavelet support and can be 6, 12, or 18.
 
 
         -i, --inverse Does inverse of fwt. 
 
         -o NUM, --order=NUM Specifies offset of the signal. If offset is not 
	               specified a default value of zero is assumed. 
 
 	-g, --gaussian Bootstrap based on a gaussian probability distribution. The mean 
	 	       is zero and the width (sigma) is taken from the third column. 
		       If a third column isn't given then the width is assumed 
 		       to be the square root of the number of counts.
 	 	       This option is incompatible with poisson bootstrap. 
 
 	-p, --poisson Bootstrap based on a poisson probability distribution 
		       (Knuth's The Art of Computer Programming, Vol. 2.)
 		       The parameter lamda is taken from the third column. 
		       If a third column isn't given then the width 
 		       is assumed to be the square root of the number of counts.
 	 	       This option is incompatible with gaussian bootstrap.
