Counts shows us how many times each different function was called, and how
many functions were called in total.

The exclusive function elapsed times show the time that each function spent 
processing code - while not in other functions.

The inclusive function elapsed times show the time that each function spent
processing code, including the time spent in other calls.

These elapsed times are the absolute time from when the function began to
when it completed - which includes off-CPU time due to other system events
such as I/O, scheduling, interrupts, etc.
