1) fixing an error in BASS that restandardized time varying covariates (e.g. distance from ice edge) at every time step,
2) format_effort now includes code to produce a Count.data object (i.e. hotspots are now processed)
3) removed set.seed from simBering.R
4) code now in place to conduct seal simulations, analyze Bering results
