can you add several tests here which go thru various indexes for index and columns

e.g. run the test somthing like:

for index in [tm.makeStringIndex, tm.makeFloatIndex ......]:
    for columns in [tm.makeStringIndex, .... ]:
           df = DataFrame(.....,index=index(h), columns=columns(w))

```

their are 6 ``make`` Index types (String,Period,DateTime,Integer,Float,Unicode)
