Creates a new Expression.

Specified by:
buildExpression in class ExpressionFactory
Parameters:
parent - The parent expression
wordParser - The text to parse based on the current position of the cursor
word - The current word to parse
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
Returns:
A new Expression representing a portion or the totality of the given text
