In salem: Provides Access to Salem Witchcraft Data

#' Simple Features data for Salem
#'
#' A dataset containing map information for the three counties
#' represented in the accused_witches data set (not including present-day
#' Maine locations) in simple features format. It also includes associated
#' data on accusations. This data should _never_ be used to analyze accusations.
#' The data is based on modern town boundaries from the Massachuessetts
#' Document Repository.  Some simple cleaning has been done to facilitate
#' basic mapping. Specifically, the names Salem Town and Salem Village are used
#' rather than the modern Salem and Danvers. Additionally, a field, TOWN_LABEL
#' is attached to the largest area for each town or community.
#'
#' Complex analyses require the sf package, but simple mapping can be
#' done using ggplot2.
