PHQL "NOT BETWEEN", Bug or Feature? :)

Hi,

QueryBuilder does not support "NOT BETWEEN". There is no function "notBetweenWhere" and an exception is thrown when I try to do it with "[and|or]Where" function.

Example:

$query->andWhere('column NOT BETWEEN 1 AND 2');

results in "Syntax error, unexpected token BETWEEN, near to ' :phb0: AND :phb1:"
