  1. Exploring a change the cost function in paramchange.c 

    I'm hoping to change the function from one assuming a 
gaussian distribution to one assuming a double exponential distribution
of errors.

  2. SIPNET Dave Moore's copy 08162007

  3. Added the following counters 

        absDifference[dataNum] = 0.0; //DM 08/16/2007
    sumData[dataNum] = 0.0;//DM 08/19/2007
    absSqDevMean = 0.0;//DM 08/19/2007

    absDifference = the absolute difference
    	between model and the data
    sumData = the sum of the data type 
    absSqDevMean = the squared difference between 
    	each data measure and the mean of that data type
    	
Added in an estimate of Beta from Hollinger and Richardson 2005
Question:  I'm not sure that the sigma calculation in the paramchange.c
			code is correct - sigma is a measure of the variability of 
			the data.  It should not be influenced by any modeled value
			The cost function as written contains deviations between the
			model and the data in both the numerator and denominator
			I'm not sure what effect this has on the optmization.

  4. Including H&R 2005 double exponential in the cost function

  5. cleared up some compiling errors 

    Question - sigma is not declared in paramchange.c ... I'm not sure where it
is declared.  But I needed to declare beta in paramchange.c

  6. Previous attempt to reformulate the cost function led to a segmentati… 

    …on fault

This attempt is simpler

sumSquares has been replaced by absDifference
in both the numerator and the denominator of the cost function
