 This class is an abstract base class that provides a basic interface 
 for all the classes that need to handle the TDirectory instance in   
 which QSigEx stores its information. A new handler can be created by 
 deriving a new class from QSigExDirHandler.                          
                                                                      

void GetObjs(TList* list, TDirectory* dir)

This function loads all the non-TDirectory derived objects of dir into
memory and fills the list with pointers of all derived objects. The
kCanDelete bit is set for all the objects that have been loaded into memory
by the function.

void GetDirs(TList* list, TDirectory* dir)

This function loads all the TDirectory derived objects of dir into memory
and fills the list with pointers of all TDirectory derived objects.

void GetListOfObjsKeys(TList* list, TDirectory* dir)

This function returns a list that is the concatenation of lists
TDirectory::GetList() and TDirectory::GetListOfKeys()

Int_t DelObjsKeys(const Char_t* name, TDirectory* dir)

This function recursively deletes the object instance and/or all the TKeys
that have the name name. It returns the number of deleted objects in the
first level (count 1 for 1 deleted folder in the first level)

Bool_t FindObjKey(const Char_t* name, const TDirectory* dir)

This function return kTRUE if dir contains a TKey or TObject with name
name

TDirectory* CopyDir(TDirectory* fromdir, TDirectory* todir)

This function is intended to copy recursively TDirectory objects
It's not implemented at the moment

TDirectory* SetDirectory(TDirectory* dir, TObject* obj)

This function allow to change the owner TDirectory of ROOT objects that have
an implemented SetDirectory function or their derived classes . The function
does nothing with other objects. It returns dir

void CheckCardNFields(Int_t nfields, Int_t min, Int_t max)

This function throw an exception if the following expression is not true:
min<=nfields<=max
