Add a method to force capitalize the next word

[printfhere]

I use this on some projects:

def start_of_sentence(self):
    """
    :return:a hidden dot to capitalize the next start of sentence
    """
    return self.nlg_tags('span', '.', style='display:none')

maybe something like that before the write and then delete the span could do the trick.
