=head2 Overview

This class is where all the work is being done and the other three classes are only 
there for support. At present there is little you can do with it other than run it. Future 
version will make subclassing of this class feasable and features like logging will be introduced.

To see how to use this class there is a simple shell in the bin directory which allows you 
to consult the example knowledge bases and more extensive documemtation in the docs directory.

There is a Ruby version that reads the same XML knowledge bases, if you are interested.

A sequence of rules for the same set can be implemented as follows: 

    $var_3->zzz( $var_1->xxx, $var_2->yyy, ... );
    $var_3->zzz( $var_4->aaa, $var_5->bbb, ... );

The subsequent application of C<< $var_3->zzz(...) >>
corresponds to "or" operations (aggregation of rules).

Only a reset can reset C<$var_3>.
