Detailed Description

The ProgressBar class which updates and prints the bar.

A common way of using it is like:
>>> pbar = ProgressBar().start()
>>> for i in range(100):
...    # do something
...    pbar.update(i+1)
...
>>> pbar.finish()

You can also use a ProgressBar as an iterator:
>>> progress = ProgressBar()
>>> for i in progress(some_iterable):
...    # do something
...

Since the progress bar is incredibly customizable you can specify
different widgets of any type in any order. You can even write your own
widgets! However, since there are already a good number of widgets you
should probably play around with them before moving on to create your own
widgets.

The term_width parameter represents the current terminal width. If the
parameter is set to an integer then the progress bar will use that,
otherwise it will attempt to determine the terminal width falling back to
80 columns if the width cannot be determined.

When implementing a widget's update method you are passed a reference to
the current progress bar. As a result, you have access to the
ProgressBar's methods and attributes. Although there is nothing preventing
you from changing the ProgressBar you should treat it as read only.

Useful methods and attributes include (Public API):
 - currval: current progress (0 <= currval <= maxval)
 - maxval: maximum (and final) value
 - finished: True if the bar has finished (reached 100%)
 - start_time: the time when start() method of ProgressBar was called
 - seconds_elapsed: seconds elapsed since start_time and last call to
                    update
 - percentage(): progress in percent [0..100]
