Changed repository structure -- moved everything under trunk.
just a tweak
Fix a parsing bug in GFunction
Improve GHistogram
Fix a regression in GInstanceRecommender
Fix a regression in GNominalToCat::untransform
Add support for new activation functions to command-line tools
Unify histogram-making code in the plot tool, and get rid of smoothing
Add a doc for visualizing data
improve some docs
Fix a bug in GBaselineRecommender, and add a unit test for it
fix a bug in graphcuttransducer
some doc work
some interface refinement for the GTransducer class. (It now 
automatically handles data type conversion, like the GSupervisedLearner 
class.)
add a doc on collaborative filtering
win64 port (fix a bunch of warnings)
add a doc on document classification
improve the interface for training from sparse matrices
give GKNN the ability to support sparse features
add a unit test for document classification (and fix some bugs it discovered)
add a testsparse tool to the waffles_learn app
Clarified comments on GRowDistance and GRowDistanceScaled
Made explicit that .h files are c++ files.  It didn't fix the problem of /// appearing in the middle of html docs, but I thought I'd leave it in, since it is correct for this project anyway.
Added overloads to GDissimilarityMetric for std::vector and also overrode operator() so that the metric also acts as a functor - for semantic sugar and for potential use in stl algorithms.
some clean-up of the GApp::launchDaemon method
add default values to the usage information so the wizard can utilize them
fix a bug preventing GKNN getting good results when trained with sparse matrices
Fix a regression in GQLearner
improve the interpolation demo
fix a synchronization issue in the interpolation demo
make the jumper demo compile again
update some usage wording
Improve how GDecisionTree handles missing values.
Fix GMatrix::replaceMissingValuesRandomly so it doesn't mess up row order.
Add a GMatrix::replaceMissingValuesWithBaseline method.
Add a GMatrix::sortPartial method, which is more efficient than GMatrix::sort.
