Detailed Description

type for returning the walker and its elements from MCPopulation

have no expectations for the validity of the references in this structure past the context it was returned in. It should not be returned by a call in a crowd or threaded context.

-luo's "fat" walker

We need this if we want to "copyFrom" the whole fat walker when it comes off the line i.e. mpi. Insuring the "fat" walker is valid at the earliest possible point seems less likely to end in tears then just calling copyFrom random other places (hopefully) in time, in order to not access an invalid walker element.
