Purpose:
To hide email addresses on your web page
from BOTS that crawl the Internet looking
for emails to add to their spam database.
Notes:
I obviously can't claim full credit for
this because it is mainly a old JavaScript
I came across some time ago. Don't remember
where I got it or who originally
wrote it. I eventually got tired of
having to add it to my pages repeatedly.
When I learned PHP I decided to make it a
function (an then rolled it into a class).
Now it is very easy to use and can actually
require less typing than the full email :-)

Yes, there is probably a purer PHP way of doing
this, but this function serves two purposes.
Purpose one, to display the email on the webpage
in the format of 'name at domain dot com' (as oppose
to name@domain.com)

Purpose two, to hide the email in the HTML code. So
instead of an email being printed in the HTML code
a Java Script Snippet is there.
