Detailed Description

A timer can be used for timing tasks. The basic usage is

Timer timer("Assembling over cells");

The timer is started at construction and timing ends when the timer is destroyed (goes out of scope). It is also possible to start and stop a timer explicitly by

timer.start(); timer.stop();

Timings are stored globally and a summary may be printed by calling

list_timings();
