Allows a TBrowser to browse non-split branches as if they were split.
The generator extracts the necessary information from the streamer info in memory (which does not have to be the same as the one on file, in case a library was loaded containing the dictionary for this type), i.e. it also works without loading the class's library.
Just as with TMethodBrowsables, if the generator finds a collection it only takes the contained objects into account, not the collections. If it identifies a collection, but cannot extract the contained type, or the contained type can be anything deriving from a TObject (like for TObjArray) or is not limited at all, no browser helper objects are created.
