Information utilities

This focuses only on tasks that involve retrieving information about the current state of a system, rather than tasks that involve changing the state of the system. This is because the scope of the former is inherently limited (at any point in time, there's only one state), while the latter is infinite (the number of potential future states is unlimited).
