title: Format and insert GeoJSON file into MongoDB
body: <p>I am new to MongoDB and GeoJSON and I am trying to import the contents of a GeoJSON file I got from the Census Reporter website into a MongoDB collection.
  Here is the beginning and end of the file:</p>

  <p>When I import the file (I'm using MongoChef), it creates a single document within the collection with: type: "FeatureCollection", "crs": {...}, and all the individual features as an array under "features".
  I'd like to have each feature in its own document in this collection. I tried removing the enclosing info and only inserting the "features" array like so:</p>

  <p>But I got a formatting error saying that there was an Unexpected Character ':' between "type": "Feature".</p>
  
  <p>Any idea how to either select which part of the original GeoJSON file to insert into the collection, or how to reformat the file to only include the data I need?</p>
  
  <p>Thanks!</p>
