Fixed main CMake file so that we can use Eigen3 from external projects
Fixed export of MVM and MMM, case when loops are not unrolled.
Fixed printing of integer typed matrices.
Fixed formatting in ExportVariableInternal
Merge branch 'master' of github.com:acado/acado
Fixed a mem leak in the symbolic core.
Updated project version info
Merge branch 'stable' of github.com:acado/acado
Added files for a CN2 solver with factorization routine.

(Copied files from the CN2 implementation).
Added the CN2_FACTORIZATION solver to the user interface
Working on the exported OCP solvers:

- moved xBoundIdx array from the main class to derived, because this
  is something condensing specific;
- cleaned a few minor thins and renamed some variables.
Fixed a minor bug when exporting argument lists.
Working on CN2_FACTORIZATION solver
Cleaning the condensing based solvers, making code a bit more readable
Working on CN2_FACTORIZATION solver
Fixed an indexing bug in the CN2_FACT...
Fixed indexing issues in CN2_FACT... solver related to the cond. Hess.
OKAY, fixed the CN2_FACT... algorithm

Forming of condensed Hessian should be fixed now.
Fixing CN2_FACT... solver. Input constrained case seems to work now.
Working on the CN2_FACT... solver

Both ctrl and state constraints should work now.
