/*! 
The transient data of the program should inherit from this base class.<br>
The transient data assumes:
<ul>
        <li> it will be created one (execute the \c ini() method)
        <li> the pointer will be preserved alive and that the data will be cleared up and filled
again. 
</ul>
<ul>
        <li> trsDataVI has a main virtual method update() that executes 
        the pure virtual methods clear() and make(). The clear() and make() should
        be implemented by the derived class. In principle, clear() clear the data
        and make() makes or fill the data. <br> Note that this method is usually null and
        replaced by the action of an algorithmVI.
        <li> There is an pure virtual method ini() to initialize the data. Most of the data is created only one,
        the pointer kept in a serverVI, and the contents of the data replaced
        every update().
        <li> For convenience we add a virtual
        method writeOut() to print out the information of the data. To be compatible
        with the messageVI writeOut() method.
        <li> The command() method executed the method of this class via their names.
        It is useful to create composite classes. It is used for example in the
        template class serverVI.
</ul>
