v.5.33.0

Moderate update

General
Starting to increased the internal precision of real and Integer numbers.
Currently the calculations doen with the command language use increases precision.
This mostly affects mmc that can now perform more than 2^32 cycles

KUPLOT
Expanded the capabilities of 'merge' to data maps as well
Expanded the capabilities of the 'func' command that uses x,y coordinates from a reference data set to data maps as well.
Added an "ice" and "thermal" color map
BUG FIX, corrected the "dat" weighting scheme in fit to use w=1/dy^2. dy is assumed to the the sigma of a dat point.

DISCUS
Added a structure export to Scatty
Modified the powder pattern calculation, to retain constant integrated intensity independent of a convolution with a profile function.
Corrected a bug in mmc related to the mode "swdisp"
CHEM the aver command used an approximation to calculate the sigmas of the average position. Corrected to give exact values.
