/* This class is used to verify the homepage link of a user profile.
* To do so, we look for rel="me" links in the given homepage, if one
* of them points to the Friendica profile of the user, a verification
* mark is added to the link.
*
* To reverse the process, if a homepage link is given, it is displayed
* with the rel="me" attribute as well, so that 3rd party tools can
* verify the connection between the two pages.
*
* This task will be performed by the worker on a daily basis _and_ every
* time the user changes their homepage link. In the first case the priority
* of the task is set to LOW, with the second case it is MEDIUM.
