branch. As some of the analysis tool packages already depend on features
that were not part of the code in this branch before.

The one thing that I didn't include from the master branch is the
const-correctness of the standalone implementation of ToolHandle<T>.
Since Gaudi doesn't force const-correctness for its own ToolHandle in
this branch, that just caused a lot of issues for the analysis code.
For no good reason. So the const-correctness issues will only be cleaned
up in the master branch properly.
