open ended question

This is a extended poll module,I mean this module depends on poll module, and the purpose of this project is to give the oportunity to add an extra text field as open answer on the votation part, beneath the default poll answers with radio button, appearing like other checkbox option with a custom label like title. This feature can be active or desactive with a simple entitled 'open ended question', that appears creating o editing a poll into the fieldset called 'poll settings', a text field appears down too, and its title is 'label' , and this is for writing the title of the open answer.
Furthermore, the new feature enter to be part of the statistics, and there is not problem desactiving the 'open ended question' checkbox, simply it works like a normal poll if this happens, and the open answer will be stored if the behavior is wanted to be active again.
