A few things tidied up re:Ripley, including removal of dependency on compiler package (not sure that speeded things up anyway)
First stab at putting ZIP model in for abundance; seems to be working (at least with detection and spatial stuff turned off). Will try to use this version to recalc post loss for misID paper

Resolved bugs:

post loss calcs screwed up; was using exp(Par$Nu[isp,itrans]) instaead of exp(Par$Nu)

if Meta$post.loss=FALSE, Obs.det, Pred.det undefined (yet returned)

Also, includes changes that resulted in errors calculating N when G was 0. and errors updating N for deletions (meta$N.transect)
ZIP now appears to be working, as does posterior loss function (error in v 2.01), including changes to let it work for strip transects irrespective of initial values for detection pars
Version 2.09 - see NEWS for 2.1. Basically
a test version prior to 2.1 CRAN release
