    Create a list of objects from multiple models/serializers.

    Mixin is expecting the view will have a queryList variable, which is
    a list/tuple of queryset/serailizer pairs, like as below:

    queryList = [
            (querysetA,serializerA),
            (querysetB,serializerB),
            (querysetC,serializerC),
            .....
    ]

    optionally, you can add a third element to the queryList,
    a label to define that particular data type:

    queryList = [
            (querysetA,serializerA,'labelA'),
            (querysetB,serializerB,'labelB'),
            (querysetC,serializerC),
            .....
    ]
