     7    Sortable mixin factory
     8  
     9    Simple sorting behavior for a list of objects. Pass the list of properties
    10    you want the list to be live-sorted based on, or use the generic sortable.js
    11    if you don’t need that.
    12  
    13    Properties to override:
    14      - sortProperty: the property to sort by
    15      - sortDescending: when true, the list is reversed
    16      - listToSort: the list of objects to sort
    17  
    18    Properties provided:
    19      - listSorted: a copy of listToSort that has been sorted
