Load All TIFF Files

//  LoadAllTIFFFilesFromFolder(pathName, nameWaveAfterFileName, displayImages)
//  This function loads each TIFF file in a given file folder into Igor.
//  The name of the TIFF file is assumed to end with ".tif".
//  pathName is the name of an Igor symbolic path or "" to get a dialog.
//  If nameWaveAfterFileName is true, the output wave name is the file name less the extension.
//  Otherwise it is something like image0, image1 . . .
//  If displayImages is true, a new image plot is created for each image.
