Added time statistics to the screen output file for timestep 0 (if Timing output frequency is zero), and add numbers and timing information to the nonlinear itterations.
New files instead of the old ones
Put more descriptive output with the nonlinear itteration counter and removed braces
Removed the timing information of the nonlinear iterations.
Added description to Timing output frequency, which explains the behavoir when the paramter is set to 0.
