********************************************************************************
All you need to do is delcare a function then:

addMod(modName, pageName);

where modName is a function and pageName is an ecwid page type. If a function returns false it'll be run until it returns true

functions get passed these:
 	      page.mode
              page.category
	      page.product

PageName options are

category
product
orderConfirmation
cart
accountSettings
orders
addressBook
checkoutSA
checkoutPD
checkoutPO
orderConfirmation
allPages


****************************************************************************
/*Test Mod*/
/*Just pops an alert on category pages containing the category number
 
tester = function (page) {
      alert (page.category);
      return true;
}

addMod(tester, "category");
