Execution timer for measuring elapsed times for code blocks written in C++11

Suppose that you want to measure the execution time for a function in a C++ code:

some_function();

By using timer, this is easily achieved:

{
  timer::Timer t;
  some_function();
}

It will automatically display the elapsed time in std::cout, for example,

[ timer : 24.601 ms ]

timer is a header-only, single-file library. It can be used by just copying timer.hpp and pasting it into your project.

Alternatively, it can be installed using cmake. If your project is also managed using cmake, ExternalProject commands are useful for including timer to your project. Another option is to use the add_subdirectory command to include this repository.
