Facet Pivot Result Parsing

Currently SolrJ is not parsing the Facet Pivot response.
It would be nice to wrap that part of the response in nice recursive objects :

…
"facet_pivot":{
"cat,popularity,inStock":[{
"field":"cat",
"value":"electronics",
"count":14,
"pivot":[{
"field":"popularity",
"value":6,
"count":5,
"pivot":[

{ "field":"inStock", "value":true, "count":5}

]},
...
