[svn-r4690]
Purpose: Feature Fix Description: Added code so that it measures the time it takes to do I/O and return that to the calling function. This code doesn't quite work yet. There is something wrong with the MPI code in the "pio_engine.c" file...I don't know what's up with it... Platforms tested: Linux
