Detailed Description

This is the class for creating benchmark and performance-profiling objects.

This type has two public methods both of which accomplish the same task of timing the user-specified procedure wrapper.
However, one (getTiming) has a function interface where the output of the method can be clearly specified, while the other (setTiming) has a subroutine interface where the output of the timing is implicitly assigned to the timing component of the parent object of type bench_type.
The former has an explicit clear calling syntax.
The latter has a more concise syntax with potentially faster runtime performance (which is likely irrelevant in almost all practical scenarios).

See also the constructor of this type.
