pymongo.errors.OperationFailure: invalid argument in geo near query: minDistance

[bigoper]

Executing the following GET request fails:
?where={"PostalCode":"33020","geo_location": {"$near": {"$geometry": {"type": "Point" ,"coordinates": [ -80.114494 , 26.48301 ]},"$maxDistance": 16000,"$minDistance": 1}}}&sort=-MatrixModifiedDT&max_results=20

-- it works when I execute the equivalent command in MongoDB

Expected Behavior

I'm expecting to get a list of document matching my query. Documents that their geo_location coordinates are within the radius

{

    "_error": {
        "code": 400,
        "message": "Query contains unknown or unsupported operators: $minDistance"
    },
    "_status": "ERR"

}

Actual Behavior

Tell us what happens instead.

pymongo.errors.OperationFailure: invalid argument in geo near query: minDistance

Environment

• Python version: Python 3.5.2
• Eve version: 0.8

[bigoper]

I've added '$minDistance' to the mongo.py class.

eve/eve/io/mongo/mongo.py

Line 125 in 7dad858

+ ["$geometry", "$maxDistance", "$box"]

It works now.
