Put up a Windows progress bar widget, update and access it.
winProgressBar(title = "R progress bar", label = "",
min = 0, max = 1, initial = 0, width = 300)
getWinProgressBar(pb)
setWinProgressBar(pb, value, title = NULL, label = NULL)
## S3 method for class 'winProgressBar'

winProgressBar will display a progress bar centred on the
screen. Space will be allocated for the label only if it is non-empty.
setWinProgessBar will update the value and for non-NULL
values, the title and label (provided there was one when the widget
was created). Missing (NA) and out-of-range values of
value will be (silently) ignored.
The progress bar should be closed when finished with, but it
will be garbage-collected once no R object refers to it.
For winProgressBar an object of class "winProgressBar".
For getWinProgressBar and setWinProgressBar, a
length-one numeric vector giving the previous value (invisibly for
setWinProgressBar).
These functions are only available on Windows.
