Secondary Indexes and Super/SubColumns, is it possible ??

Hi,

I've managed to get secondary indexes working on Normal Columns. I've even
managed to get multiple IndexExpressions to work when querying.

However, its not clear to me

1) If I should be able to have a secondary index on a sub-column of a
super-column

2) Assuming 1 is supported, how to specify it in the column_metadata section
of the yaml

No, this isn't supported.
