[Users] Output timer reports to a file instead of stdout

[Erik Schnetter]

Thorn CactusUtils/TimerReport can output periodic timer reports of a  
Cactus simulation.  This lists all routines which are called from  
schedule.ccl, plus information from all available timers for these  
routines, which includes normally the amount of wall time and CPU  
time spent in these routines.  This information can be very useful to  
determine where time is spent in a simulation.

Thorn TimerReport now understands a new parameter "out_filename",  
allowing to redirect these reports into separate files.  This is  
convenient because it allows easily accessing timer reports from all  
processors, not only the root processor.  It also makes it easier to  
find the timing information without having to look through all of  
stdout.

You can use this thorn e.g. with the following settings:

ActiveThorns = "TimerReport"

TimerReport::out_every    = 512
TimerReport::out_filename = "TimerReport"

This will create output files called "TimerReport.0000" etc., one  
file for each processor.
