#1200 handle objects in context

[hudajkhan]

Updating context rendering component to handle objects that come back as values in context.
For example, broader concepts in genre form lookup come back as
values": [
{
"uri": "http://id.loc.gov/authorities/genreForms/gf2011026049",
"id": "gf2011026049",
"label": "Animated films"
}
]

The code now looks for "label" in the value object and displays that. If there is no label but there is a uri, it will display that instead, and if neither, then it will display a stringified version of the json object
