o added four new functions to assess sample sizes of animal tracking data (boot_overlap, boot_area, asymptote, percent_vol). o added a new example data "curtis" o added a new argument "type" in the depthfilter function. o renamed some functions (ddfilter.loop -> ddfilter_loop; ddfilter.speed -> ddfilter_speed; dupfilter.exact -> dupfilter_exact; dupfilter.qi -> dupfilter_qi; dupfilter.space -> dupfilter_space; dupfilter.time -> dupfilter_time, distantfilter -> distfilter). o renamed an argument in ddfilter (maxvlp -> vmaxlp). o improved the R documentations.
