Detailed Description

Makes a tree out of C++ standard types and vectors of C++ standard types

This class, which is an EDAnalyzer, takes the same "keep" and "drop" outputCommands parameter as the PoolOutputSource, making a tree of the selected variables, which it obtains from the EDM tree.

See the file python/test_cfg.py for an example configuration.

See the file doc/README for more detailed documentation, including advantages, disadvantages, and use philosophy.
