#' @title Tabular Text Input Controls
#'
#' @description Create a table of input controls for entry of unstructured text values
#'
#' @param inputId the \code{input} slot that will be used to access the value.
#' @param label Display label for the control, or \code{""} for no label.
#' @param value Initial value
#' @param width The width of the input, e.g. \code{'400px'} or \code{'100\%'}
#' @param leftLabel Should the label column be the left column or the right column.
#' \code{TRUE} puts the label on the left column.
#'
#' @return \code{textInput_cell} returns a character vector the length of \code{inputId}.
#'
#' \code{textInput_row} returns a data frame with two columns and a row for every
#' element in \code{inputId}
