Importing data sets with many dimensions causes import problems and resulting data sets cannot be deleted

[GoogleCodeExporter]

Importing a dataset with many dimensions (in one report, about 200) causes an 
overflow in the key 
length that is not caught. There needs to be more checking (and error handling) 
on import. Also, 
delete needs to be more robust to be able to delete half-broken data sets.

The new data model fixes this. The limitation is no longer the potential number 
of combinations, but the actually 
existing number. This should push the envelope beyond most practical data sets.
