Detailed Description

A class to compute statistics about quantities of interest.

Statistics stat();

The Statistics class can be used to keep track of the minimum, maximum, average of quantities of interest.

To report the results just call:

stat.report("Code ID");

Thou can also provide an additional std::ostream& parameter to report() to redirect the logging on a different output. Also, you can use the get_total/min/max/average() methods to get the individual numeric data, without all the details of the logging. You can also extend Statistics to implement your own logging syntax.

To report all the measurements:

stat.report_all();

Same as above, you can redirect the output by providing a std::ostream& parameter.
