+TODO
+       Read PlotFile's.
+       Add to ctsim export of imagefiles to standard graphic formats.
+       Use FFTW library in imagefile.cpp
+       
+3.0alpha1 - Released 12/30/00
+
+       * Added PlotFile class to system, used by if2 and ctsim for row
+       and column plots and comparison plots
+
+       * ctsim: Added image comparison statistics and image subtraction
+
+       * ctsim: Added plotting of rows & columns with y-axis scaling 
+
+       * ctsim: Added row and column plot comparisons between two image
+       files.
+
+       * ctsim: Added "Process" menu to image file display with math
+       functions. Added 2-dimensional inverse Fourier to math
+       functions. Added support for complex (real/imaginary) images.
+
+       * mathfuncs.cpp: Reworked statistics algorithm to share between
+       imagefile and plotfile classes.
+
+       * imagefile.cpp: Fixed scaling bug when rasterizing Phantom with
+       nsamples > 2.  Added generic mage math functions, moved from
+       if1.cpp and if2.cpp to imagefile.cpp. Added support complex
+       images.
+
+       * array2dfile.cpp: Added code to support complex (real/imaginary)
+       images.
+
+       * if1: Updated to handle error conditions, such as sqrt of a
+       negative number. Converted to use new ImageFile math functions.
+       
+       * if2: Updated to output plot files and use new ImageFile class
+       math functions
+
+       * if1: Updated to use new ImageFile class math functions
+
+       * ezplot: Reworked to better store colors/linestyles/symbols with
+       individual curves. Improved display of labels and ticks. Updated
+       to use POL class member variable. Updated to more C++ conventions.
+
+       * pol: converted to C++ class. Extracted HashTable to separate
+       class.
+       
+       * sgp: Added linestyle settings
+
