#' Lists the given anchors in the given transcript.

#' @param labbcat.url URL to the LaBB-CAT instance
#' @param id A transcript ID (i.e. transcript name)
#' @param anchor.id A vector of anchor IDs (or a string representing one anchor ID)
#' @param page.length In order to prevent timeouts when there are a large number of
#' matches or the network connection is slow, rather than retrieving anchors in one
#' big request, they are retrieved using many smaller requests. This parameter
#' controls the number of anchors retrieved per request.
#' @return A named list of anchors, with members:
#' \itemize{
#' \item{\emph{id} The annotation's unique ID},
#' \item{\emph{offset} The offset from the beginning (in seconds if it's a
#' transcript of a recording, or in characters if it's a text document)}
#' \item{\emph{confidence} A rating from 0-100 of the confidence of the offset,
#' e.g. 10: default value, 50: force-aligned, 100: manually aligned}
