class BreadcrumbManager

Provides a breadcrumb manager.

Can be assigned any number of BreadcrumbBuilderInterface objects by calling the addBuilder() method. When build() is called it iterates over the objects in priority order and uses the first one that returns TRUE from BreadcrumbBuilderInterface::applies() to build the breadcrumbs.
