tidwall cf7f49fd9b Add field path queries for json and comparison operators 
It's now possible to query a JSON field using a GJSON path.

   SET fleet truck1 FIELD props '{"speed":58,"name":"Andy"}' POINT 33 -112

You can then use the GJSON type path to return the objects that match the WHERE.

   SCAN fleet WHERE props.speed 50 inf
   SCAN fleet WHERE props.name Andy Andy

Included in this commit is support for '==', '<', '>', '<=', '>=', and '!='.
The previous queries could be written like:

    SCAN fleet WHERE props.speed > 50
    SCAN fleet WHERE props.name == Andy

tidwall f24c251ee6 Allow for multiple MATCH patterns 
Each MATCH is inclusive OR, thus

    WITHIN fleet MATCH train* truck* BOUNDS 33 -112 34 -113

will find all trains and trucks that within the provides bounds.

tidwall 241117c7ba Added BUFFER option for Within and Intersects 
This commit allows for buffering any GeoJSON object.

For example:

    INTERSECTS fleet BUFFER 1000 OBJECT {...LineString...}

This will buffer add a 1 kilometer buffer to a linesting and
search the 'fleet' collection for all objects that
intersect the buffered linestring.

This commit also allows for performing INTERSECTS with a POINT
type. Thus allowing for a polygon-over-point operation, which is
an inverted point-in-polygon.
