Log:


Remove the combine_range method from the range_op class, and move it to ranger
as a method, and just specialy handle AND amnd OR

Modify the calculation of AND and or to get ranges for both TRUE and FALSE
on both sides of the expression, then merge them as approriate for
the AND or OR to corectly reflect the way the condition works.
