In rsgeo: An Interface to Rust's 'geo' Library

#' Simplify Geometry
#'
#' Simplifies LineStrings, Polygons, and their Multi- counterparts.
#'
#' Simplify functions use the Ramer–Douglas–Peucker algorithm. Functions with `vw` use
#' the Visvalingam-Whyatt algorithm.
#'
#' For more see [`geo` docs](https://docs.rs/geo/latest/geo/index.html#simplification).
#' @param x an object of class of `rsgeo`
#' @param epsilon a tolerance parameter. Cannot be equal to or less than 0.
#' @export
#' @rdname simplify
#' @returns an object of class `rsgeo`
#' @examples
#' x <- geom_linestring(1:100, runif(100, 5, 10))
#'
#' simplify_geoms(x, 3)
#' simplify_vw_geoms(x, 2)
#' simplify_vw_preserve_geoms(x, 100)
