#' Block Sums
#'
#' Calculates block sums (i.e. moving sums but for non-overlapping intervals) or
#' maximum block sum. For optimal speed, use \code{integer = TRUE} if \code{x}
#' is an integer vector and \code{integer = FALSE} otherwise. If
#' \code{length(x)} is not an exact multiple of \code{window}, the last partial
#' segment is dropped.
