add  #pragma link C++ global ROOT_TMath as suggested by Philippe. This avoids via the header guard to re-include the definition of TMath.h when running in CINT.

Introducing a parallel unzipping algorithm for pre-fetched buffers. Since we already know what buffers are going to be read, we can decompress a few of them in advance in an additional thread and give the impression that the data decompression comes for free (we gain up to 30% in reading intensive jobs).

The size of this unzipping cache is 20% the size of the TTreeCache and can be modified with TTreeCache::SetUnzipBufferSize(Long64_t bufferSize). Theoretically, we only need one buffer in advance but in practice we might fall short if the unzipping cache is too small (synchronization costs).

This experimental feature is disabled by default, to activate it use the static function TTreeCache::SetParallelUnzip(TTreeCacheUnzip::EParUnzipMode option = TTreeCacheUnzip::kEnable). The possible values to pass are: TTreeCacheUnzip::kEnable to enable it,TTreeCacheUnzip::kDisable to disable it and TTreeCacheUnzip::kForce to force it. Since it will only work if you have more than one core, the TTreeCacheUnzip::kForce option is useful to run it even if you have only one cpu (to measure the overhead, for example).

TPRegexp
========

1. Modularized Match() and Substitute() functions so that the low-level work
   is done by MatchInternal() and SubstituteInternal().

2. Added function TString GetModifiers() that translates from bit-flag
   options back to perl-style option characters.

3. For all functions that do actual matching replaced the default value
   of 'Int_t nMatchMax' argument from 30 to 10. PCRE internals require
   the index buffer to be 3-times the number of allowed matches. This
   multiplication is now performed in individual functions and nMatchMax
   is really the number of allowed matches. Two function calls in 
   TString passing this number explicitly have been updated.

TPMERegexp
==========

New sub-class of TPRegexp with API closer to PERL.
Supports main Perl operations using regular expressions (Match,
Substitute and Split). To retrieve the results one can simply use
operator[] returning a TString.

  The routine has been modified from the original hdiff to use always the effective entries for normalizing the 
   max distance. 
  Now in princile it could also be used also for comparing an histogram with a function created as an histogram 
  with zero errors (equivalent to option F1 or F2 in the original HDIFF.

Main changes are: 

  TMath: 

        from David: The following methods now have additional interface working with Iterators as well:  
		MinElement
		MaxElement
		LocMin
		LocMax
		Mean
		GeomMean
		RMS
		BinarySearch
		Sort -> (changed to SortItr)
       	- use now std in binary search algorithm. Old algorithm failed some tests and it is found to be a 
           little bit slower 
       	- do not use std instead in LocMin and LocMax since generic std algorithm is slower on 64 bit arch. 
       	- TMath::PoissonI 
            fix a problem for large values, by using directly the TMath::Poisson implementation
       	- TMath::Landau and TMath::Landau
  		remove duplications by using directly ROOT::Math::landau_pdf and ROOT::Math::landau_cdf
	- TMath::Prob
   		use ROOT::Math::chisquared_cdf_c  (gives also less rounding errors  for small values)
	- TMath::GammaDist
   		use ROOT::Math::gamma_pdf , implementation now returns correct value, 0,  for large values of 
		shape parameter instead of nan
	- TMath::LogNormal:   
  		use ROOT::Math::lognormal_pdf 

	- compile TMath dictionary with -O2 
	- fix a warning in -Wshadow      

        - TMath.h is now  reordered by functionality and alphabetical order

  test: 
	various improvement from David, see http://root.cern.ch/viewcvs?rev=22880&root=root&view=rev	

  - add dictionary for the enumeration used in the Integration class 
  
  - from David: some clean up of Minimizer class (remove typedef definitions)
