#' export_data
#'
#' Export data in CSV format from local ODK Briefcase Storage directory to a
#' specified destination directory and a specified file name
#'
#' @param target Path to directory of ODK Briefcase \code{.jar} file. Directory
#' path should match directory path used when calling \code{get_briefcase()}.
#' If ODK Briefcase \code{.jar} file was downloaded manually from \url{https://opendatakit.org},
#' \code{target} should match the directory path where \code{.jar} file has
#' been downloaded into.
#' @param briefcase Filename of the downloaded ODK Briefcase \code{.jar} file.
#' Default is \code{odkBriefcase_latest} to match the default filename used
#' by \code{get_briefcase()}. If ODK Briefcase \code{.jar} file was
#' downloaded manually from \url{https://opendatakit.org}, filename should
#' match the default filename used by Open Data Kit which is usually
#' "ODK Briefcase vX.Y.Z Production.jar" where vX.Y.Z is the version number
#' @param id Form ID of form to be pulled
#' @param from Path to source ODK Briefcase Storage from which to extract data.
#' This should match directory path specified when making a call to \code{pull_remote()}
#' or \code{pull_local()}
#' @param to Destination directory to save output data file
#' @param filename Filename of output CSV data; default is
#' \code{paste(id, "_data.csv", sep = "")}
#' @param start Include data from submission dates after (inclusive) this start
#' date in export to CSV; format <yyyy/MM/dd>
#' @param end Include data from submission dates before (exclusive) this date in
#' export to CSV; format <yyyy/MM/dd>
#' @param overwrite Overwrite existing output data in destination
#' directory with the same filename; default is FALSE
#' @param exclude Exclude media files on export; default is TRUE
#'
#' @return CSV file in destination directory containing data from the pulled
#' forms
#'
#' @examples
#' # Export data from a specified ODK Briefcase Storage directory to current
#' # working directory with a filename called "test.csv"
#' \dontrun{
#' dirPath <- tempdir()
