dois RadioButtons, que são Par ou ìmpar,
este programinha roda aleatoriamente,
num tempo determinado pelo evento OnTimer,
um contador numa na faixa muito ampla,
e no término, isto é, quando o botão parar
é pressionado ele informa se o último número
é par ou ímpar, indicando num label se o usuário
acertou ou não na escolha.
