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.

out-comment the use of method computeGeodesicDifference.  It currently doesn't work for all target spaces

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