/**
 * HTTP cookie specification: RFC6265
 * 
 * A cookie list is a JSONObject whose members are presumed to be cookie
 * name/value pairs. Entries are unescaped while being added, and escaped in 
 * the toString() output.
 * Unescaping means to convert %hh hex strings to the ascii equivalent
 * and converting '+' to ' '.
 * Escaping converts '+', '%', '=', ';' and ascii control chars to %hh hex strings.
 *
 * CookieList should not be considered as just a list of Cookie objects:
 * - CookieList stores a cookie name/value pair as a single entry; Cookie stores 
 *      it as 2 entries (key="name" and key="value").
 * - CookieList requires multiple name/value pairs as input; Cookie allows the
 *      'secure' name with no associated value
 * - CookieList has no special handling for attribute name/value pairs.
