#' Load a plate layout file and a file specifying the machine runs
#' See the provided example files for the layout and machine run file formats.
#' @title Create a well data frame
#' @param plateLayoutFile a file containing the plate layout.
#' The file must contain a column named \code{plate} and a column named \code{well}
#' @param machineRunFile a file containing the machine runs
#' The file must contain columns named \code{directory}, \code{filename} and \code{plate} specifying
#' the directory and filename of the data for the corresponding run. The column \code{use} is optional.
#' If present, only rows with \code{use == TRUE} are put into the dataframe. 
#' @return an object of class well and data.frame
