#' Project for web function
#'
#' This function allows you to reproject spatial data to WGS84, which is the projection required for webmaps such as leaflet.js
#'
#' You can either use the default WGS84 projection or supply your own.
#'
#' @param dat Expects input of sp object: point, polygon, etc.
#' @param projection Defaults to WGS84
#' @keywords ggplot NZ maps
#' @examples
#' webprojected <- proj4web(anyprojection)
#' @import rgdal
#' @import sp
#' @import mapproj
#' @export
