* added Cloning factory aka abstract factory
  it will be used in the boundary conditions classes
* testsuite/lifecore/test_factory.cpp has a test for clone factories
  now
* test_factory is now enabled

this is the first COMMIT that makes boost:: a requirement !

factories rely on boost::function<> for functors.

still unfinished (need interface for modifyBC())

updated NEWS

updated NEWS with work from Simone and Gilles (only the solvers in lifealg ;) )

added Alexandra and Gilles in the AUTHORS file

and updated NEWS

as of now only 0.x.y where y will be mostly 0 unless a subrelease .y should be made
because of a bug found in the 0.x branch

ensight7-write.hpp to lifefilters and renamed it
ensight7Writer.hpp. fixed compilation for MP solvers ;)

darcySolver is far from being ready for life/lifesolver

and already changes are pouring in thx to CW

make distcheck runs completely without failure with "--enable-opt"

However masstransport fails without --enable-opt. We need to investigate
this. perhaps Martin can help. It is very suspicious that depending
on compiling options the code crashes (seg fault)

wait for the build tonight to see if everything is ok

  it is easier to make script blah blah blah ...
