logisticdupbyx_fast

As <code>logisticdupbyx</code>, but faster when distance is a covariate
(but no interactions with distance occur.

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.
