Returns columns needed by functor from multilevel dataset
To access tables with multilevel column structure, the `MultilevelParquetTable`
or `DeferredDatasetHandle` need to be passed either a list of tuples or a
dictionary.
Parameters
----------
data : `MultilevelParquetTable` or `DeferredDatasetHandle`
columnIndex (optional): pandas `Index` object
either passed or read in from `DeferredDatasetHandle`.
`returnTuple` : bool
If true, then return a list of tuples rather than the column dictionary
specification. This is set to `True` by `CompositeFunctor` in order to be able to
combine columns from the various component functors.
