8 Fixed Array2dFile::labelsCopy()
9 Added copy constructor and assignment for Array2dFileLabel class
10 Added Timer to if-2.cpp and ifinfo.cpp
11 Added beginning of frequency-based (DFT & FFT) filter to SignalFilter
12 Added option processing for filter-method for pjrec to choose
13 between convolution, dft, & fft filtering
14 Fixed format string for EZPlot so axis labels now print
17 Rewrote Array2dFile class to be non-templated
18 Rewrote Array2dFile class to make reads and writes atomic. No disk files are kept open.

21 Renamed ctrec to pjrec, sample-ctrec.sh to sample-ctsim
22 Added signature tag and creation date/time to projection files
25 Standardized string option processing by classes. All classes use character strings
26 to select options rather than numeric constants. Added fail() and failMessage()
27 methods to verify that objects are created correctly by character strings.
28 Hid C++ assignment and copy constructors in classes that should not have assignment/copy
29 Rewrote ImageFile class
30 Started support for dmallocxx library, not finished

37 Moved conversion filter name/id to Filter class
38 Moved conversion backprojection name/id to Backproj class
39 Added MPI broadcasting of strings
42 Merged proj_reconstr into class Projections
43 Used auto_ptr in Projections::reconstruct to make sure destructor is always called
44 Code cleanup in projections.cpp
45 Moved conversion of phantom names/id to Phantom class
48 Converted projection files to C++ library with frnetorderstream
49 Converted image files to C++ library with frnetorderstream
50 Converted filter and convolution to object-oriented code
51 Changed default image file to float from double -- Changable in imagefile.h
52 Optimized image file writing on little-endian architectures
53 Updated README and INSTALL
56 Reorganized source files
57 MPI bug fixed to phm2pj.cpp
60 Reorganized include files
61 Fixed const pointers in strfuncs
64 Renamed directories, moved source files, combined source files
65 to change from 6 libraries to 3 libraries (libctsim, libctsupport,
69 Skip versions to make version 2.0 the first fully C++ version
70 Renamed Raysums to Projections throughout files
71 Renamed Detector to Scanner
72 Converted Scanner and Projecions to full object-oriented
75 Converted Phantom and PhantomElements to Object-Oriented
76 Converted Detector to Object-Oriented
79 Improved Integer backprojection method
80 Fixed nearest neighbor to be truly nearest neighbor
81 Made linear interpolation more integer arithmetic -> speed improvement
82 Finished converting all C files to C++
83 Converted all use of malloc/free to C++ new/delete
84 Began object-oriented conversion of Phantom and Projection structures
87 Converted MPI data structures to C++ object
88 Made ImageFile directly inherit from Array2dFile
92 Portable IF (image file) format implemented with objects (SDF removed)
93 - Now all data files are cross-platform compatible
94 Converted from MPI to MPI++
95 Converted backprojection to object-oriented
96 Removed MTX from libkmath as no longer need -- replaced with C++ matrices
