### Choix de la periode d'echantillonnage
#' @title Select validation sample
#' @description This function is used by the MMCNS interface to let the user select the validation sample.
#' @param data dataframe from which first and last available dates should be extracted.
#' @param leftMargin the padx value of tk widgets in the first column of the tab.
#' @param tm a one row dataframe containing text to display in the interface.
#' @param win1 frame of the uHMM interface containing main tabs.
#' @param uHMMenv environment in which data and intermediate results are stored.
