Generate a progress bar string.

    Arguments:
        tag (string): Label to print before the bar (i.e. Train, Valid, Test )
        epoch (int): current epoch to display
        minibatch (int): current minibatch to display
        nbatches (int): total number of minibatches, used to display relative progress
        cost (float): current cost value
        time (float): time elapsed so far in epoch
        blockchar (str, optional): character to display for each step of
                                   progress in the bar.  Defaults to u2588
