The "API" page has been changed by PaulCarey.


  A `Deletion` encapsulates an operation that will delete all columns matching the specified
`timestamp` and `predicate`. If `super_column` is specified, the `Deletion` will operate on
columns within the `SuperColumn` - otherwise it will operate on columns in the top-level of
the key.
