Inline entities on paragraphs

You can also include entity mentions directly on paragraph responses using ?include=entities: 
curl "https://api.urantia.dev/paragraphs/74:1.1?include=entities"
This adds an entities array to each paragraph with the id, name, and type of every entity mentioned: 
{
  "data": {
    "id": "2:74.1.1",
    "text": "Adam and Eve arrived on Urantia...",
    "entities": [
      { "id": "adam-and-eve", "name": "Adam and Eve", "type": "being" },
      { "id": "urantia", "name": "Urantia", "type": "place" }
    ]
  }
}
Works on all paragraph-returning endpoints: /paragraphs/*, /papers/:id, /search, and /search/semantic. For search endpoints, pass "include": "entities" in the request body.
