what does this function do? // Enumerate and possibly display the animated GIF filenames in GIFS directory int enumerateGIFFiles(const char *directoryName, boolean displayFilenames) {

numberOfFiles = 0;

File directory = SD.open(directoryName);
if (!directory) {
    return -1;
}

File file = directory.openNextFile();
while (file) {
    if (isAnimationFile(file.name())) {
        numberOfFiles++;
        if (displayFilenames) {
            Serial.println(file.name());
        }
    }
    file.close();
    file = directory.openNextFile();
}

file.close();
directory.close();

return numberOfFiles;
