Describe Wikka Handlers here. What are they? How are they invoked? What is the difference between a handler and an action? How are they related?

Wikka Handlers provide functionality that generally acts on an entire page or affects the wiki as a whole in some way. You could say that handlers "handle" something for the user, such as deleting a page, modifying Access Control Lists (ACLs), or showing page history. Wikka actions affect a part of a wikka page. Actions are usually inserted into a page along with all of the other markup. When the page is viewed/rendered, the action is "executed" and it's output is displayed.

Page Handler List Describe each handler
    1. You are the page owner and you are logged in.
    1. You are logged in as the admin user for the Wikka Wiki. (The link doesn't appear if the page is owned by "nobody". Click the "Take ownership" link at the bottom of the screen to take ownership of the page before trying to modify the Access Control List.)

XML Handler List Describe each handler. How are xml handlers different? (See: Mod015fFilesAction)
    1. Sample download link generated by handler: http://localhost/HandlerInfo/files.xml&action=download&file=aFile.pdf
    1. Sample delete link generated by handler: http://localhost:8080/wikka/wakka.php?wakka=BraveTerry/files.xml&action=delete&file=52287.pdf
