Searchable mixin
Simple search filtering behavior for a list of objects.
Properties to override:
- searchTerm: the string to use as a query
- searchProps: the props on each object to search
- listToSearch: the list of objects to search
Properties provided:
- listSearched: a subset of listToSearch of items that meet the search criteria
