A GeoJSON point may be provided as the first and only argument for
2dsphere queries. This single parameter may be a GeoJSON point object or
an array corresponding to the point's JSON representation. If GeoJSON is
used, the "spherical" option will default to true.
This method sets the "near" option for the geoNear command. The "num"
option may be set using {@link Expr::limit()}. The "distanceMultiplier",
"maxDistance", "minDistance", and "spherical" options may be set using
their respective builder methods. Additional query criteria will be
assigned to the "query" option.
