Not tested yetfix memory leak by using an auto_ptr for the inner solverimplement derivativeOfDistanceSquaredWRTSecondArgument()rewrite the gradient assembler such as to demand the derivative of the _squared_ distance from the target space. Unlike the distance itself, the squared distance is differentiable at zeroimplement matrix assembly by simply returning the identity matrix. This should a sort of projected gradient descent. It is too late at night for me to compute the actual matriximplement gradient of distance functionassemble gradient of functionalbugfix: properly set matrix and rhs sizesbugfix: set member 'assembler_'activate the solve()-method and make it compileinherit at least from NumProcimplement the exponential mapimplement the exponential map. Use a FieldVector to store the data instead of Dune::arrayadd more constsimplement the Riemannian distancemethod value() is construn and don't crashstart a generic implementationimplement the distance metricactivate evaluate() method againUnit vectors in R^n, or, equivalently, members of S^{n-1}added missing call-by-referenceTest RealTuples as wellA rudimentary class implementing tuples of real numbers as a Riemannian manifold. Mainly for testingfix a warningFactor out the actual test into a separate method. This paves the way for testing more target spacesremove code for interpolation via recursive geodesics. It is invariant under permutation of the verticesadd missing headerUse shapefunctions from dune-localfunctions instead of dune-discMake rodobstacle use the RigidBodyMotion classIntroduce a 2d specialization for Rotationthrow an exception if direction is not a descent directioneasier testing: start from the straight solutionThe parameter file is now called rodobstacle.parsettear out dune-disc function transfer code. No replacement yet, thoughdon't supply default arguments to ConfigParserremoved rods.pc, added rods.pc.inadded rods.pc, complemented configure.ac and Makefile.amdune-solvers --> dune/solvers
