#58: Fit causes 'out of memory' for modest dataset sizes

 fit creates a matrix of size m x m during the calculation of error bars,
 where m is the number of data points. With just 12,000 data points this
 consumres more than 1GB of RAM !

 If there are many parameters, but only a few allowed to vary, then
 unnecessary memory is used: m x n where n is the total number of
 parameters, not the number free to vary. With a 3000x300 matrix, more than
 1GB of RAM will be needed if 140 parameters, even once the first problem
 is solved.
