* This "page" page is the display component of the ez-pages module
* It is called "page" instead of "ez-pages" due to the way the URL would display in the browser
* Aesthetically speaking, "page" is more professional in appearance than "ez-page" in the URL
*
* The EZ-Pages concept was adapted from the InfoPages contribution for Zen Cart v1.2.x, with thanks to Sunrom et al.
