Implement a request from Tancredi Carli:
" we are working on a new classification method that
is based on Probability Density Estimation and
a self-adapting phase space binning in n-dimensions.
This method will extend and complement the PDE-RS method already
implemented in TMVA/RooT. We are using the TFoam class.
Originally, the TFOAM class was written in order to provide a
fast and efficent Monte Carlo integration. However, with the some minor
modifactions (mainly in the TFDISTR external user defined function),
the TFOAM class is also an ideal structure to store the probability
densities and
a very good algorithm to do a automatic binning. We have performed first
tests and the method is competitive.
We would like now to proceed and to implement this new
method in TMVA. We have written a class PDE-foam that
derives from the TFOAM class.
However, some minimal change to the TFOAM class a needed:
- change "private" to "protected" to give access to private variables
by derived classes
- change "//" to "//!" (these changes apply to the comment
behind the declaration of the variable "TFoamIntegrand *fRho;")
- declare all Methods "virtual"
With these changes, also future ideas could use the TFOAM class."

A number of small changes:
- made many getters const
- changed many includes in the headers to forward declaration
- removed "const" from non- pointer and ref basic types in function arguments
- added //author lines
- corrected cvs ident line to include "root/foam"

New package FOAM:
// Authors:
// S. Jadach and P.Sawicki
// Institute of Nuclear Physics, Cracow, Poland
// Stanislaw. Jadach@ifj.edu.pl, Pawel.Sawicki@ifj.edu.pl
//
// What is FOAM for?
// =================
// * Suppose you want to generate randomly points (vectors) according to
// an arbitrary probability distribution in n dimensions,
// for which you supply your own subprogram. FOAM can do it for you!
// Even if your distributions has quite strong peaks and is discontinuous!
// * FOAM generates random points with weight one or with variable weight.
// * FOAM is capable to integrate using efficient "adaptive" MC method.
// (The distribution does not need to be normalized to one.)
