In pretty much any practical circumstance, whenusing `ListAll` or
`ListAny`, you have a list of types on which you run some sort of
predicate on each item in the list to determine whether any or all of
the items match the predicate. To make this easier, add a second
argument to `ListAll` and `ListAny` to provide a predicate that will
automatically be added.
If no predicate is given, then the operation is run directly on the
list. This is implemented by just using an identity operation.
These new features to VTK-m lists allow you to compute a single value
from a list. `ListReduce` allows you to compute a value based on a
predicate. `ListAll` and `ListAny` use this feature to determine if all
or any of a list of `true_type` or `false_type` objects are true.
