#define PROF_TIME_UNIT struct timeval

This file implements the macros for reading and converting system time. A total of six macros must be implemented:

PROF_TIME_UNIT - the data type for storing a time value PROF_DURATION_UNIT - the data type for storing an interval or a duration PROF_RESET_DURATION(DURATION) - resets a duration to zero PROF_GET_TIME(TIME) - gets the current system time PROF_ADD_DURATION(DURATION, START_TIME, END_TIME) - adds the interval between two time values to a duration PROF_CONVERT_TO_MICROS(DURATION,DOUBLE) - converts a duration to microseconds

Conversion is separate from read time, since we don't want to do it every time we read time, but only when we need to return it.
