In DistanceDevelopment/dsdata: Distance sampling workshop data

#' Duiker camera trap survey
#'
#' Study took place in Tai National Park Cote d'Ivoire in 2014.  Filmed Maxwell's duikers (Philantomba maxwellii) were assigned to distance intervals; recorded distances are the midpoints of the intervals. This data includes only observations recorded at times of peak activity.
