58 Standardized string option processing by classes. All classes use character strings
59 to select options rather than numeric constants. Added fail() and failMessage()
60 methods to verify that objects are created correctly by character strings.

98 to change from 6 libraries to 3 libraries (libctsim, libctsupport,
102 Skip versions to make version 2.0 the first fully C++ version
