 // Class for parsing lists of integers into ranges.
 //
 // The anti-phishing and anti-malware protocol sends ASCII strings of numbers
 // and ranges of numbers corresponding to chunks of whitelists and blacklists.
 // Clients of this protocol need to be able to convert back and forth between
 // this representation, and individual integer chunk numbers. The ChunkRange
 // class is a simple and compact mechanism for storing a continuous list of
 // chunk numbers.
