That makes the code more readable, which is more important to me than
speed.  The stuff is difficult enough as it is.

Compute the local corrections in local coordinates on the tangent bundle now, instead of using the embedding in the surrounding space

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

[[Imported from SVN: r5959]]

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