Sift Indices
Sift a list of items into two lists based on a set of indices, those that are at the indices and those which are not. Each resulting list will have the same length and order as the input list but will be filled with null placeholders for items that went to the other list.

|---|---|---|---|
| List | L | List of items to sift | Generic Data |
