ToDo:
- put version number in text file and copy it into any of the files.
- (TJ) change root address of FreeHEP repository
- (TJ) Aida web pages should refer to users, ref and dev implementations.
- (TJ) Aida web pages should go in the same repository

- Use of backing store for large numbers of histograms?

Questions for AIDA 2.0 (Boston):
- are the arrays as input and output in C++ actually vectors?
- what about iterator in ls() methods?
- if so, should we use the same in Java?
- missing functions getName/getLabel/Title in JTuple?
- find name for developers interface package
- discuss new interfaces
- name, label, which one is ID
- policy for creating with respect to the tree
- policy for duplication of objects
- policy of name, label default

Questions for AIDA 2.3 (GB)
- Pertinency of IAnnotation. IAnnotation over IHistogram AND ICloud, 
  IFunction, ITuple ? Do we expect to save / retreive annotations ?
- What is missing in order to have interoperability between
  histogram implementation / plotter implementation ?
- I<Bare>[Histogram, Cloud, Function].
- IHistogram1D.clearFit.
- IManagedObject.tree() to get the ITree of an object.
- Have enum instead of string for function type, fitting type, plotting
  parameters, etc...
- document aida-config command.

Questions for AIDA 2.3 (MD)
- Should we have an "aida.h" file which includes all "AIDA/*.h" files
  so that the user/tester only has to include one, and so that we can
  easily test that the .h files of aida do not conflict with themselves?
- How does one add an Annotation to a Histogram, and should the annotation()
  method not return a reference rather than a pointer (just like: axis() does)?
- The Iterator class, which we currently do NOT have but do use, should
  it be some class from STD? If not the FreeHEP implementation includes 
  an Iterator.h file which is coupled to java via a JIterator, which 
  connects to a Java Iterator. The next() method currently returns 
  a pointer, should that be a reference? 
  Should we use this Iterator class?
- The Tuple class seems to return an object of class NtupleEntry. If we 
  need this class, may I suggest to name it TupleEntry, or rename Tuple
  to NTuple.
- The Tuple class has a method for filling bytes and one for characters.
  In java char is 16 bit Unicode, which may not be very useful for Tuples,
  but it could be mapped (via ASCII) to the fill(char) version of C++. 
  The other method in java would be fill(byte) which would map to 
  fill(unsigned char) in C++. Currently the byte method is uncommented
  in the ITuple.h interface.
- The java method createPlotter in the PlotterFactory seems to take no 
  arguments, while the C++ method takes (int, char**). Should these be 
  passed?
