Functions
void	ROOT::Internal::TreeUtils::ClearMustCleanupBits (TObjArray &branches)
	Reset the kMustCleanup bit of a TObjArray of TBranch objects (e.g.

std::vector< std::string >	ROOT::Internal::TreeUtils::GetFileNamesFromTree (const TTree &tree)

ROOT::TreeUtils::RFriendInfo	ROOT::Internal::TreeUtils::GetFriendInfo (const TTree &tree, bool retrieveEntries=false)

std::vector< std::string >	ROOT::Internal::TreeUtils::GetTopLevelBranchNames (TTree &t)
	Get all the top-level branches names, including the ones of the friend trees.

static void	GetTopLevelBranchNamesImpl (TTree &t, std::unordered_set< std::string > &bNamesReg, std::vector< std::string > &bNames, std::unordered_set< TTree * > &analysedTrees, const std::string friendName="")

std::vector< std::string >	ROOT::Internal::TreeUtils::GetTreeFullPaths (const TTree &tree)

std::unique_ptr< TChain >	ROOT::Internal::TreeUtils::MakeChainForMT (const std::string &name, const std::string &title)
	Create a TChain object with options that avoid common causes of thread contention.

std::vector< std::unique_ptr< TChain > >	ROOT::Internal::TreeUtils::MakeFriends (const ROOT::TreeUtils::RFriendInfo &finfo)
	Create friends from the main TTree.
