Changed
- The `IVector`, `IRawVector`, `IMatrix` and `IRawMatrix` interfaces have been removed for performance reasons,
see https://github.com/robotology/idyntree/issues/98#issuecomment-158823148 . If you want to write generic
code in C++ you can rely on templates, and on Matlab and Python you can rely on the native dynamic type system.
- All the core classes that have a fixed size (`Position`, `Rotation`, `Transform`, `SpatialMotionVector`, etc, etc) are
not initialized by their empty constructor for performance reasons, see https://github.com/robotology/idyntree/issues/98#issuecomment-158795881 .
From now on, make sure that initialize them before any use. Most of those classes should have a `zero()` method to
zero its content, or a `Zero()` static method that return a instance with its content set to zero.
For ensuring that no regression happened on the iDynTree codebase, a CMake advanced option `IDYNTREE_RUN_VALGRIND_TESTS`
has been added to make that no use of initialized memory occurs.
