The dynamic boxes (modules) for the visualization are managed here.
They are used to show colored squares, dependent on the value of a communication object.
The dimensions of a box are set in the visualization. In principle, any square within the Visu area is possible.

They are initially defined without a communication object.
The communication object is then assigned later on using the module.

A module is composed of the

standard color, which is assumed when none of the conditions are met

and

squares that are displayed depending on a condition.
