Added inequality operators to the vector class
Symbolic core updated.
Added new ctor to the Matrix class; init with scalar value
Refactored curve and user interface classes.
OK, giving up... Vector and Matrix class have the stupid init function.
Integrators updated to the new API.
Updated examples for the new API.
BDF integrator backwards mode does not work

+ I screwed up the forward mode, jacobians are re-computed always
+ Sparse LU mode does not work.
Fixing matrix and vector classes
Fixed the qpOASES interface
Fixed the rest of OCP+Simulation classes to the new matrix-vector API.
Examples updated to the new matrix-vector API
