Like ui-sref-active but applies to sibbling states as well (requires UI-router).
How to use
<span class="cui-desktop-menu__option" ui-sref="applications.myApplications" ui-sref-active-nested="active">Link to my apps</span>
This will apply the class
active to the element everytime the user is in the state "applications" or any child state of applications (sibblings of applications.myApplications).
