[dune/copasi/utilities]
add directory with utilities
[src/turing_problem_ccfv]

add program, which is able to solve turing problem
using finite volume methods

- includes local operator for arbitrary nr. of components
- FV has 1 DOF p. cell p. component
- includes ReactionAdapter, class which implements reaction term

I think this example can be extended for arbitrary systems
[src]

changes regarding program structure
in [src] are programs
in /dune/copasi/ are utilities which are shared by programms
I renamed this dune-module to dune-copasi
