    Class designed for having a set of priorities
    If a resource is requested to lock from the UI, it means
        that it is ready to be locked immediately.
    But if a resource is requested to retrieve from search_string,
        then it should include the priority level from 1 to any integer you decide
    For Example, a group could decide to priority their queues that are pending for a request
        in the following way:

    UI - 0
    PRODUCTION TESTING - 1
    LOAD TESTING - 2
    DEVELOPMENT TESTING - 3
