 ### The pagemenu and pageitems directives
 The module provides two directives, *pageitems* attribute and *<pagemenu>* tag. The *pageitems* tag will parse the included HTML and query for items with a certain class. The menu will then be generated in the DOM where you put the *<pagemenu>* tag from that list of items.
