TestTopOpeTools
Provide Trace control on packages involved in
topological operations kernel, from Draw command interpretor.

They may be used by users of topological operation kernel, such as :

* topological operation performer,
* hidden line removal performer,
* fillet, chamfer performer

Trace control consists in management of
control functions, activating/desactivating execution of
instructions considered as purely PASSIVE code,
performing dumps, prints, and drawing of internal objects
dealed by some topological operation packages.

All of the Trace controls in top.ope. kernel
are enclosed by the C conditional compilation statements :
#ifdef DEB ... #endif

The "Traced" packages of topological operation kernel are :
- TopBuild
- TopOpeBRepTool
- TopOpeBRepDS

How to use the Trace :
----------------------

In a Test.cxx program using the Draw command interpretor, dealing
a set of commands theCommands (Draw_CommandManager theCommands) :
TestTopOpeTools_Array1OfMesure
TestTopOpeTools_HArray1OfMesure
TestTopOpeTools_Mesure

about one specific entity, producing a model with the
abnormal result

basic features from user callable forms
