        Specified by:
        buildExpression in class ExpressionFactory
        parent - The parent AbstractExpression
        wordParser - The text to parse based on the current position of the cursor
        word - The current word being parsed
        queryBNF - The BNF grammar that was used to identifier this factory to be capable to parse a portion of the query
        expression - During the parsing, it is possible the first part of an expression was parsed which needs to be used as a sub-expression of the newly created expression
        A new AbstractExpression representing the portion or the totality of the text held by WordParser starting at the cursor position
