This library provides a text mode progressbar. This is tipically used
to display the progress of a long running operation, providing a
visual clue that processing is underway.

The ProgressBar class manages the progress, and the format of the line
is given by a number of widgets. A widget is an object that may
display diferently depending on the state of the progress. There are
three types of widget:
- a string, which always shows itself;
- a ProgressBarWidget, which may return a diferent value every time
it's update method is called; and
- a ProgressBarWidgetHFill, which is like ProgressBarWidget, except it
expands to fill the remaining width of the line.

The progressbar module is very easy to use, yet very powerful. And
automatically supports features like auto-resizing when available.

    The term_width parameter may be an integer. Or None, in which case
    it will try to guess it, if it fails it will default to 80 columns.

    The simple use is like this:
    >>> pbar = ProgressBar().start()
    >>> for i in xrange(100):
    ...    # do something
    ...    pbar.update(i+1)
    ...
    >>> pbar.finish()

    But anything you want to do is possible (well, almost anything).
    You can supply different widgets of any type in any order. And you
    can even write your own widgets! There are many widgets already
    shipped and you should experiment with them.

    When implementing a widget update method you may access any
    attribute or function of the ProgressBar object calling the
    widget's update method. The most important attributes you would
    like to access are:
    - currval: current value of the progress, 0 <= currval <= maxval
    - maxval: maximum (and final) value of the progress
    - finished: True if the bar is have finished (reached 100%), False o/w
    - start_time: first time update() method of ProgressBar was called
    - seconds_elapsed: seconds elapsed since start_time
    - percentage(): percentage of the progress (this is a method)
