#' Update a Worker QualificationType
#'
#' Update characteristics of a QualificationType.
#'
#' A function to update the characteristics of a QualificationType. Name and
#' keywords cannot be modified after a QualificationType is created.
#'
#' \code{updatequal()} is an alias.
#'
#' @aliases UpdateQualificationType updatequal
#' @param qual A character string containing a QualificationTypeId.
#' @param description A longer description of the QualificationType. This is
#' visible to workers. Maximum of 2000 characters.
#' @param status A character vector of \dQuote{Active} or \dQuote{Inactive},
#' indicating whether the QualificationType should be active and visible.
#' @param retry.delay An optional time (in seconds) indicating how long workers
#' have to wait before requesting the QualificationType after an initial
#' rejection. If not specified, retries are disabled and Workers can request a
#' Qualification of this type only once, even if the Worker has not been
#' granted the Qualification.
#' @param test An optional character string consisting of a QuestionForm data
#' structure, used as a test a worker must complete before the
#' QualificationType is granted to them.
#' @param answerkey An optional character string consisting of an AnswerKey
#' data structure, used to automatically score the test
#' @param test.duration An optional time (in seconds) indicating how long
#' workers have to complete the test.
#' @param auto A logical indicating whether the Qualification is automatically
#' granted to workers who request it. Default is \code{NULL} meaning
#' \code{FALSE}.
#' @param auto.value An optional parameter specifying the value that is
#' automatically assigned to workers when they request it (if the Qualification
#' is automatically granted).
#' @param verbose Optionally print the results of the API request to the
#' standard output. Default is taken from \code{getOption('pyMTurkR.verbose',
#' TRUE)}.
#' @return A data frame containing the QualificationTypeId of the newly created
#' QualificationType and other details as specified in the request.
