check.bounds

Simple internal function to check that the optimisation didn't hit bounds.
Based on code that used to live in <code>detfct.fit.opt</code>.

Animal abundance estimation via conventional, multiple covariate
and mark-recapture distance sampling (CDS/MCDS/MRDS). Detection function
fitting is performed via maximum likelihood. Also included are diagnostics
and plotting for fitted detection functions. Abundance estimation is via a
Horvitz-Thompson-like estimator.
