For this now the TangentVector class of S^n has only n components,
while the EmbeddedTangentVector class still has n+1.
The code around it needs to be fixed accordingly.

[[Imported from SVN: r5963]]

remove the possibility to solve the inner problem with a truncated cg.  It never really worked and complicates the code

new method to setup a solver using a truncated cg as the inner solver.  This compiles, but it doesn't work yet

[[Imported from SVN: r4105]]

[[Imported from SVN: r4104]]

[[Imported from SVN: r4103]]

make the inner solver a pointer to a generic Solver class, in anticipation of using a truncated cg there

RodSolver is now called RiemannianTrustRegionSolver, and can be parametrized with the TargetSpace.  Some remains of RigidBodyMotion are still there, though.

The class 'Configuration' is now called 'RigidBodyMotion', and can be parametrized by the space dimension
