public final class TAPConfiguration
extends java.lang.Object
```
Utility class gathering tool functions and properties' names useful to deal with a TAP configuration file.
This class implements the Design Pattern "Utility": no instance of this class can be created, it can not be extended, and it must be used only thanks to its static classes and attributes.
