Remove all references to boost, using C++11 instead. Changed all Eigen types passed by value (http://eigen.tuxfamily.org/dox-devel/group__TopicPassingByValue.html). Small portability tweaks to build on windows.
Annotate classes and methods with platform dependend export macro. Allows DLL's to be created on windows.
Support C++11 in Clang and GCC 4.6.
Use C++11 for portable sleep.
Merge WinDev branch.
