> A new get call that lets you get all the columns between colStart and colEnd like:
> get_slice_by_name_range(string tablename,string key,string columnFamily_column, String columnNameStart = "" , String columnNameEnd)
> This would be particularly useful if you were encoding some information in the column names, and couldn't leverage just offset and count to get at the correct set of columns (eg all columns starting with "b").
> It might be fine to support this call only on name sorted column families and throw an UnsupportedException for other columnfamilies.
