| public boolean | hasScoreCurve(android.net.wifi.ScanResult result)Returns whether there is a non-null score curve for the given ScanResult.
A null score curve has special meaning - we should never connect to an ephemeral network if
the score curve is null.

| public boolean | isScoredNetwork(android.net.wifi.ScanResult result)Returns whether there is any score info for the given ScanResult.
This includes null-score info, so it should only be used when determining whether to request
scores from the network scorer.
