Initial stub version
Added .gitignore file.
Added Poco project submodule at the current stable version 1.4.6.
Derived a subclass FriendsOrFoesApp of Poco::Util::Application
Added Clone class and implemented commandline options.
Added default values and finished handling configuration/command-line options.
Copied configuration information to the output file.
Added abstract virtual classes Cell and Population.  In particular the geometry
is left abstract.
Made the void * argument the first argument to the func argument of each of the
fold methods.  This way func can be a pointer to a method of some class.
Added method get_affected_by_neighbors() to Cell.
Added an abstract class ReplicationRecord to record a replication.  Added
abstract virtual methods check_for_space_to_replicate() and replicate() to the
Population class.
Added a method kill() to class Population.
Removed method get_affected_by_neighbors() from Cell and added method
increment_fitness_by().  Added field neighbor_affect_cell_func to class
Population.  Added method update_all_fitnesses() to class Population, which
updates the fitnesses of all cells using neighbor_affect_cell_func.
Made update_fitness() a method of class Population.
Added third-party file gsl-sprng.h.  Authored by Darren Wilkinson, this file
was downloaded from
http://www.staff.ncl.ac.uk/d.j.wilkinson/software/gsl-sprng.h
Moved 3rd-party file gsl-sprng.h to include since it is a header file.
Added third-party library sprng2.0b to the repository.  Need to compile it with
MPI support.
Changes to get sprng2.0 to compile.
Ditching sprng2.0, will try RngStreams instead.
Added the third-party RngStream parallel random number generator by Pierre
L'Ecuyer, downloaded from
http://www.iro.umontreal.ca/~lecuyer/myftp/streams00/c++/.
