Fixed comparison of Orange.data.Instance when the domain is empty.

Urgent bugfix: Refactor CRC variables from unsigned long to unsigned int to make it work properly on 64-bit machines (with 64-bit Python and libraries). Fixes #1146.
Janez Demšar
Added add_CRC(const int) to remove casting when computing a checksum for TExample
Janez Demšar
Renamed Domain.classes to Domain.class_vars; now they always exist, but may be empty Domain's constructor now has a new keyword argument class_vars ExampleTable now has pickClass for picking a new class and putting the current class attribute to class_vars
Janez Demšar
Added multiple classes (Ticket #1012)

Replaced Variable->name with setter and getter. Interface to Python remained the same.

- changed licenses to GPL 3.0

- fixed problems with exporting the getExampleID function
Janez Demšar
- added id's to examples

- fixed an exception message

- crc now also adds meta attributes and handles missing values differently
Tomaz Curk
need this before Qt4 become trunk (main branch)
Janez Demšar
- TExample::operator [] const now returns undefined if the specified meta attribute does not exist - added TExample::getValue and TExample::getMetaIfExists which do the same
Janez Demšar
- TExample::TExample doesn't append meta attributes if they are marked as optional
Janez Demšar
- Example.compare and Example.compatible now have an additional flag telling whether to observe the class or not
Janez Demšar
- Example(PDomain) has previously put DC for meta attributes, causing incompatibilities at merging; changed to DK.

This is a merge of dll-try branch. From this version on, it is possible to write C++ modules that import and use Orange's objects. This required a huge number of global changes, in particular in garbage collection, C++ to Python interface and vector (replaced by our own implementation that is more suitable for dll exports). Changes needed for dll exports: - ORANGE_API was added to virtually all classes and to some functions, so…

- hopefully recovered everything that was lost at the (unsuccessful) attempt to make orange compilable with gcc 3.4.4

- DistanceMap now correctly squeezes - meta attributes that are registered in the source but not in destination domain are now NOT copied when examples are converted
Janez Demšar
- fixed the grid problem in Heatmap - added upper/lower matrices in DistanceMap - worker on continuizers

- fixed a minor bug preventing compilation on Solaris

Resolved minor issues for compiling on Linix

These are changes from Houston, Feb 04. I haven't checked whether it compiles on Linux; I guess the code for domain multi-mapping would have problems. - Added loess with Gaussian kernels (statc.lwr) - TClassifierFromVar(-FD) now have a flag transformUnknowns that allow them (if set) to transform unknown values (instead of leaving them unknown, as before) - orange.Example can now be given a domain and a list of examples to fetch values from (need to check this, though) - STRINGVAR moved to straingvar.hpp - ValueFilter (and consequently, Preproces…

- purified association rules - induction of classification rules is now smarter - added sparse rules (written by Matjaz Jursic) - added .basket format - TExample constructors now accept an optional argument telling whether to initialize/copy meta values

- written or_random_shuffle to replace random_shuffle which is not the same on MSVC and Linux - changes in RandomGenerator which should not affect anything - fixed BiModalDiscretization - other minor changes in classes for discretization
