List with extended functionality: slices of ViewList objects are child lists, linked to their parents. Changes made to a child list also affect the parent list. A child list is effectively a "view" (in the SQL sense) of the parent list. Changes to parent lists, however, do *not* affect active child lists. If a parent list is changed, any active child lists should be recreated. The start and end of the slice can be trimmed using the `trim_start()` and `trim_end()` methods, without affecting the parent list. The link between child and parent lists can be broken by calling `disconnect()` on the child list. Also, ViewList objects keep track of the source & offset of each item. This information is accessible via the `source()`, `offset()`, and `info()` methods.
