This feature adds a horizontal bar under the top menu which tracks the
vertical scroll position. Such a feature can be useful to represent how
much is left to read on the current page more aesthetically.
As this is an optional feature, `enable_progressbar` must be set to
`true` in `_config.yml` to activate the functionality.
I am not the original author of this code. I just made it compatible
with the current version of the template at the time of this commit. The
original code was most likely authored by Pankaj Parashar in this
[post](https://css-tricks.com/reading-position-indicator/) made a few
years before the first inclusion in an `al-folio` site. Then, the code
was adapted for compatibility with the template at Anthony Plantanios'
site. Finally, I did
the last updates to have the code fit the new conventions used in the
project.
This was discussed in #557
