This model is designed to investigate assessment of nest site size by
ants (particularly L. albipennis), as described in Mallon & Franks
(2000) and Mugford et al. (2001), particularly why a two-pass
assessment strategy is used instead of a one-pass strategy. The model
was used to produce the results presented in Marshall et al.  (2003).
