Add support for all STL collections, including collections
of collections.
TTree has been extended to support split mode for most STL
collections.
The test program bench.cxx/TBench.cxx has been extended to test
STL collections of objects or pointers.

as well as as the new version of ClassDef/ClassImp.
With the additions to the I/O, it is now possible to generate
a dictionary for classes not instrumented with ClassDef.

The new I/O scheme still requires more work due
to portability problems and the size of the dictionaries.

should be able to support foreign not-ROOT instrumented classes.
More information will come later.
This patch is tentatively put in the CVS head to facilitate
testing on all platforms.

// this test program compares the I/O performance obtained with
// STL vector of objects or pointers to objects versus the native
// Root collection class TClonesArray.
// Trees in compression and non compression mode are created for each
// of the following cases:
//  -vector<THit>
//  -vector<THit*>
//  -TClonesArray(TObjHit) in no split mode
//  -TClonesArray(TObjHit) in split mode
// where:
//  THit is a class not derived from TObject
//  TObjHit derives from TObject and THit
//
// The test prints a summary table comparing performances for all above cases
/ (CPU, file size, compression factors).
// Reference numbers on a Pentium III 650 Mhz machine are given as reference.

This new test is also to test the portability of STL on the upported platforms.

Makefile.in modified to include the new benchmark.

To run the test suite, simply execute bench.
