Added support for serializing dlib::int64
Modified
/trunk/dlib/serialize.h
/trunk/dlib/test/serialize.cpp
Revision: 3525
Date: Mar 05, 2010 (01:40:16 UTC) 
Fixed spelling error
Modified
/trunk/dlib/svm/svm.h
Revision: 3523
Date: Mar 03, 2010 (03:29:59 UTC) 
Switched the sparse vectors all over to unsigned integral keys and changed
the definition of what is officially a sparse vector to say that unsigned
integral keys are required.  Having this requirement is nice because it creates
a simple correspondence between dense vector index values and sparse vector keys.
The previous sparse vector definition was just excessively generic.
