       This package implements a factory to create type and operation based terms.  Those terms are used to
       access data from the table(s) - either when evaluating the where clause or returning column data.

       The concept of a factory can be studied in DesignPatterns by the Gang of Four. The concept of using
       polymorphism instead of conditions is suggested by Martin Fowler in his book Refactoring.

buildCondition
       Builds a condition object from a given (part of a) where clause. This method calls itself recursively for
       predicates.
