Reset function for monitor template

[GoogleCodeExporter]

A simple reset function that resets norms and counters would be useful for 
repeated Krylov method use. 

So:
cusp::default_monitor<ValueType> monitor(b,k, tol);

The function

monitor.reset()

will set:
r_norm=std::numeric_limits<Real>::max()
iteration_count_=0;

Just insert this into monitor.h

monitor.reset()
{
r_norm=std::numeric_limits<Real>::max()
iteration_count_=0;
}

Ok, ya I did pretty much the same thing. I have attached a patch with the above 
change if anyone is interested. It worked fine for me, but I haven't "properly" 
tested it, it is only 3 lines of code though.
