put brood cannibalism back in.

IF we take the 33% cap off of the pollen foraging population, we get jaggedness again, but this creates really nice pictures- except for the honey storage
uses pulled out vector from hsurf and interp1 function- not enough honey storage this way for hive to survive

If I remove honey consumption altogether, and just let them collect it, I get some pictures that look a lot like the poster.
I think no big changes.
fixed honey issue, no discontinuities, no starvation

Still doesn't quite match up with Wanyi's model, but very close
less forager death, parameter change
negative effect of nursing load on survivorship added back in

This causes us to run out of foragers for some reason :(  not good- but only happens briefly, doesn't cause population to get jagged or crash
