Post-constructor.
The normal implementation should call simply inherited::build(), then this class's build_(). This method should be callable again at later times, after modifying some option fields to change the "architecture" of the object.

// ### This method should do the real building of the object,

// ### Typical situations include:
// ### - Initial building of an object from a few user-specified options
// ### - Building of a "reloaded" object: i.e. from the complete set of all serialised options.
// ### - Updating or "re-building" of an object after a few "tuning" options have been modified.
// ### You should assume that the parent class' build_() has already been called.

Override this for runnable objects (default method issues a runtime error).
Runnable objects are objects that can be used as *THE* object of a .plearn script. The run() method specifies what they should do when executed.
