Now program can display any pair dimension as table form.
time/airport time/airplane time/airport
Some output might looks strange because row name too long.
Need to implement drill up/down.
You can use currentDim1 and currentDim2 to refer where you at. Ex, you
are using time/airport. currentDim1 = year means you are displaying all
year. If currentDim1 = month, you need to add a value which can hold
year you select to drill down, so you can use it to query.
