- Added a SimTK_FORCE_INLINE macro that can be used (judiciously) to override a compiler that fails to inline a method when it should have. I saw VC++ 2013 decide not to inline a trivial operator[] method which resulted in poor performance.
- Modified the performance-critical Array_ classes to make use of the new macro and verified that VC++ obeyed and that performance improved.
- Fixed Doxyfile to ignore the new macro.
