Display predicted scene graph

[adaminsky]

Notes:

• The predicted scene graph is generated using a slightly modified version of https://github.com/KaihuaTang/Scene-Graph-Benchmark.pytorch with the help of Yinjun.
• The above model produces custom_prediction.json and custom_data_info.json which unfortunately do not follow the same format as the provided ground truth in scene_graphs.json.
• I have very limited knowledge of JQuery, but I know that the way I load the JSON files is wrong because it is happening in parallel which causes it to attempt to output the data before all of it has been fully loaded.
• Running this crashed my computer because the custom_prediction.json file is too large.
