[dune-fem] Fem timer

[Agnese, Marco]

Ok it worked ;)

I will update a little the documentation of the timer.

Thank you Tobias,
Cheers,
Marco.

Hi Marco

Your code should look like:

/* Begin */
#define FEMTIMER
#include <config>

#include <dune/fem/misc/femtimer.hh>

int main ()
{
unsigned int id =
FemTimer::addTo( "Compute timer",1);
FemTimer::start(id);

// do something

FemTimer::stop(id);
FemTimer::print(std::cout);

/* End */
}

The femtimer is itself is a singleton.
You can also set the macro FEMTIMER within the makefiles, this ensures
that it is defined within each included header, which seems not to be
the case, otherwise the complier should complain about the private
default constructor FemTimer femtimer();

Best Tobias
