 // PhishingTermFeatureExtractor handles computing term features from the text
 // of a web page for the client-side phishing detection model.  To do this, it
 // takes a list of terms that appear in the model, and scans through the page
 // text looking for them.  Any terms that appear will cause a corresponding
 // features::kPageTerm feature to be added to the FeatureMap.
 //
 // To make it harder for a phisher to enumerate all of the relevant terms in
 // the model, the terms are provided as SHA-256 hashes, rather than plain text.
 //
 // There is one PhishingTermFeatureExtractor per RenderView.
