\brief Types for the interaction module.
\par Description
Primary formats for communication between a regular program and the interaction module.
\remarks Began as struct cartesoid and evolved into the following types. This is the most important part of the solution as it determines the how the program is organized.
\pre ISO C++ 11 or later compliant compiler with an available C++ 11 STL implementation.
\version 4
